As the only bit of apparel that’s with you for every step of your race, the tri-suit is a fundamental piece of triathlon gear. Here’s our guide to the best tri-suits on the market, whether you’re racing sprint or Ironman, on a budget or looking for aerodynamic gains.
What is a tri-suit?
A tri-suit is a garment specifically designed for racing all three disciplines of triathlon. Made of a similar quick-drying fabric to swimwear, it’s flexible, hydrodynamic and aerodynamic so it can cater for the demands of swimming, cycling and running. It includes a pad/chamois for comfort on the bike leg, but this pad shouldn’t obstruct your final run leg.
What tri-suit should I buy?
As the only piece of triathlon gear that’ll be with you from the starting horn until the finishing chute, the right tri-suit is a key purchase: too tight, baggy, poorly made or slow to dry and you’ll be flirting with a DNF instead of reaching for a personal best.
It also depends on what distance you’re planning to race and whether comfort or speed is your priority, and race conditions. The main options are vested, short-sleeved and those designed especially for Ironman, and there are advantages and disadvantages of each.
See below for more information on choosing the best tri-suit for you.
How are the tri-suits tested and reviewed?
The tri-suits here were all given multiple tests on the swim, bike and run to find the best one. Key factors included breathability, how fast they dried, chafing (or lack of), pocket sizing and accessibility, and the effectiveness of the leg grippers and zippers.
The pad was assessed for how quickly it dried after the swim, its ability to provide comfort on the bike leg and whether the size impacted on the run.
The price, aesthetics, durability and aerodynamics were also considered, as was the versatility of each suit. Many of the Ironman tri-suits were also tested for their aerodynamic abilities at the Silverstone Sports Engineering Hub’s wind tunnel.

Best short-sleeved tri-suits
Elbow-length suits are equipped for the needs of the modern-day triathlete: shoulders and sleeves help to protect your skin; improved pads aid comfort; and fabrics are designed to be both hydro- and aerodynamic.
On top of all that, manufacturers have thought about the practicalities of getting them on and off and have started getting creative with their designs, producing tri-suits for a variety of distances. Time, then, to take a look at some of the best triathlon short-sleeved tri-suits on the market…
Best short-sleeved tri-suits for men
Orca Athlex Aero Race Suit

- £149
We don’t look at the price tags of these suits until after the testing has finished and I figured the dimpled fabrics, superior meshing and breathability of the new Athlex would put it above the £200 barrier.
Happily, it’s well below that. The cooling material composition and sizeable white back panel also lends this one to warmer racing climes.
Those aero dimpled sleeves are the business, while the pad is supportive yet supple on the bike and run, respectfully. The covered rear pockets and stretchy material make this the one for non-wetsuit swims, although the swallow depth of the two rear pockets means that taller gels can dislodge.
Points are also lost for lack of a zipper garage and the relatively basic leg grippers tend to move up and down the legs when cycling, though this is a mild irritation rather than a full-blown catastrophe.
Verdict: A brilliant suit that’s speedy yet supportive and is a good choice

Tri-Fit Evo Next Gen

- £189
Tri-Fit’s debut Evo suit was just a couple of tweaks away from near maximum marks when we tested it in 2019 and the acclaim keeps flowing with the Evo Next Gen in 2022.
The suit builds on what made the Evo so good, the combo of Italian and German fabrics providing a silky-smooth internal experience and aerodynamic ribbed outer, with smartly-placed underarm mesh vents and superior leg grippers, adding to the winning composition.
The Next Gen again utilises the floating back pocket trick, which stops the pockets pulling on the suit when loaded, and yet there are swim benefits thanks to the side entry points.
That said, stuffing gels into the stealthy hip pockets in T1 at speed is tricky. The pad is a reliable one and the finishing quality has been improved, but some might want more padding for Ironman. It features a great full-length zipper and garage, though.
Verdict: A classy contender with silky-smooth fabrics and well-crafted tri flourishes

Aptonia Short-Distance

- £39.99
Decathlon’s in-house brands largely score well on these pages for their functional design and affordability, yet Aptonia’s trisuits haven’t yet answered the demands of tri racing.
Until now, with the new ShortDistance Trisuit. Neat triathlon touches abound, with a mesh strip along the spine for ventilation, leg pockets for gels, a fulllength zip guard and a covered rear pocket for swim gains.
We even felt some compressive properties in the thighs. Of course, there are compromises. We’d prefer more than the single back pocket, the material composition and design can’t compete with Santini et al, and the elastic grippers are pretty limited.
The legs come up quite short as well. Given their quality bike kit, we’d like to see what Decathlon’s Van Rysel brand could do with twice this budget, but this is still a strong beginner suit with a welcome price.
Verdict: A few compromises, but we’d recommend this as a debut tri-suit for beginners

Santini Aahonoui Viper

- £279
This Ironman collaboration from top-end Italian brand Santini instantly shows its class, with silky smooth materials and lengthy ribbed sleeves aimed at increasing the aerodynamic prowess.
So far, so expected. It continues to impress in the innovative details, the best being a grippy exterior that runs on the outside of the high-quality and supportive pad to prevent saddle slippage after the swim.
And yet it’s not all good. The lack of a breakaway zipper is an oddity on a suit with Ironman racing intentions in 2022, and the irritable inside of the zipper also tends to graze the skin on the bike and run.
The duo of rear pockets is also a little shallow for securely holding taller energy gels and the leg grippers, although seriously effective, may be a little too tight for those with stockier legs. Stylish design, however.
Verdict: Sleek and stylish, bu zipper troubles and a worry and rear pockets are a little shallow

Zoot Elite Triathlon Aero Racesuit

- £232
Zoot’s famously bold designs are missing from this sleek pinstripe suit and we miss them. Luckily the Elite has a trick or two up its aero sleeves, with a full-length zipper for speedy toilet stops, Zoot’s reliably smooth Italian fabrics and a sizeable mesh back for warmer climes.
There’s plenty of ribbed ‘Highway Aero’ fabric targeted at maximising any drag reduction, although we haven’t seen any wind tunnel or CfD data and we couldn’t detect recovery gains from the touted compressive fabric.
Those who prefer a plumper pad and are racing longer than Olympic distance may well want a beefier chamois, although the positive is that it’s near invisible on the run.
We’d prefer flatlock internal seams and more than one rear pocket. For all its class, the Elite struggles to justify its price tag.
Verdict: Classy fabrics but there are more versatile and better value suits here

Dhb Aeron Ltd Edition

- £125
One look at this limited-edition tri-suit makes you think there’s something a little unique and quirky behind it. So it’s no surprise to find that it’s the brainchild of one of Britain’s finest long-course triathletes, Joe Skipper.
Joe was heavily involved in the design and construction of the suit as part of his partnership with dhb and has been wearing the exact same one in racing. It’s obviously suited to long distance, with a chamois that doesn’t chafe, even after multiple hours in the saddle.
Meanwhile, two rear pockets provide accessible and secure storage. There’s plenty of shoulder flex, and the wide arm and leg grippers mean there’s very little movement on the run.
If there’s one downside it’s that the bottom of the zip rubs slightly, even if there is no pull down through the shoulders. Of all the features that makes this typically Joe, it’s the design – loud and stylish.
Verdict: a striking suit that’s ideal for long distance, but the zip could be improved

Zoot Ltd Tri Aero Tokyo

- £180
The Tokyo visual theme may have been extended into 2021, but the LTD Tri Aero from Zoot is still a good all-round tri-suit with little to fault.
It definitely delivers a nod towards longer-distance triathletes thanks to its superior pocket space; the rear pocket is complemented by two tight side pockets on either leg that are perfect for gels and solve the storage issue better than many.
The fit is also reasonable and didn’t inhibit run form, while the SBR 2D pad is agreeable on both the bike and run, including for extended periods.
The Italian Primo fabric is comfortable and breathable, while the technology employed in the suit should result in aerodynamic returns.
The full-length zipper and design appeal of the suit help to deliver a solid all-rounder, which is well-crafted and does a lot of things well, rather than one or two things that are truly outstanding.
Verdict: A high price but great style, and the versatility ensures something for everyone

Raceskin Funky Skull

£175£120
In the Funky Skull Speedsuit, Raceskin has produced a tri-suit that lives up to its name. The titular Skull design is striking and typical of the brand, which is celebrated for its custom tri kit.
There’s plenty more to like as well, such as generous movement in the shoulders, well-positioned rear pockets and an effective zip cover that’s so good it makes you wonder why you don’t find it everywhere, while the full-length zipper allows for easy toilet stops.
Yet there are downsides. The pad is double density but didn’t prove as comfortable as others on test for longer rides, suggesting it’s more appropriate for short-course racing.
The Lycra fabric and flatlock seams are comfortable, but the sizing was an issue as it was a little short in the body for us, producing a slight ‘dragging down’ effect on the posture when running.
Verdict: great visuals and a zip guard, but the pad means this suit is better for shorter distances

Assos Triator SS Speedsuit

- £380
Swiss cycling brand Assos has made a bold debut into the premium tri market with the attractive Triator Speedsuit. It’s clear from the chamois that this is a suit designed by people who spend time on bikes, offering a perfect blend of comfort and minimalism for long-distance racing.
The suit itself feels like a second skin, with honeycomb textured arms for enhanced aerodynamics and a scooped neckline which offers zero restriction.
Our only gripe’s the shoulders being set a little too narrow, which caused some tightness on the swim. The ultralight material dries exceptionally fast, with vented sides aiding heat dissipation and a special ice pocket in the neck for cooling during hot racing.
We like the graduated leg compression, offering all day support, and in addition to two rear pockets, the suit has two small pockets hidden inside the front.
Verdict: This suit oozes quality, a real luxury item for those who can afford it

Castelli PR Speed Tri Suit

- £300
Castelli’s gone all in on aerodynamics, so much so the PR Speed would be illegal in a cycling event. In practice, this means the wind-tunnel-tested design has elbowlength striped silicone arms which aim to reduce drag on the bike.
Ultra-thin 50 denier fabric on the upper body means the fabric is quite literally barely there. This gives maximum cooling, but we’d question its sun protection capabilities.
Despite offering great shoulder flexibility, the upper body is on the small side, with the neck pulling us down when standing and the jersey-style top spontaneously unzipping on occasions when the zip’s nudged.
The chamois is also minimalist in design, but it still provided comfort and support in testing. Though not marketed as such, the legs feel compressive and supportive even on tired legs, and the dual rear pockets provide plenty of room for several gels or bars.
Verdict: A tri-suit for serious racing, with a luxurious feel and ample storage

Huub Her Spirit Long Course Tri Suit

- £119.99
The energetic and fun colour scheme makes you want to get racing just by looking at this suit, the result of a collaboration between Huub and Her Spirit.
Lightweight and flexible, the suit feels like a second skin and provides UV protection for long days in the sun. An open-neck design allows great freedom of movement.
The chamois feels thick and supportive on the bike, but may be larger than ideal when it comes to the run. Despite the leg grippers looking thin, they hold firm and don’t give any unwanted bulging.
Although not littered with aero features, the suit felt slippery in both the air and water. The only negative was the pocket size, with only enough room for two gels in each of the two pockets.
Despite this, as the cheapest suit on test, it wasn’t out of place with those twice the price.
Verdict: A colourfil, well-designed tri-suit at an affordable price from a top tri brand

Stolen Goat Upstart Tri-Suit

- £160
Stolen Goat’s vibrant design is striking, but this tri-suit’s about more than just its looks. ‘Airstripe’ sleeves claim to save eight to 10 watts per arm – the equivalent of a disc wheel – with the close-fitting upper body maximising aerodynamic gains.
Thankfully, the four-way stretch material and the split front design allow full flexibility, meaning that the suit doesn’t feel restrictive despite its slim fit.
The Upstart also offers UV protection, while the breathable fabric kept us cool throughout testing. The two large rear pockets comfortably hold at least four gels each.
Wide grippers stay in place, but as the legs come up shorter than others on test, they sit more in the meaty part of the leg, resulting in tightness and a slight bulging effect.
The Upstart’s available in an impressive seven sizes, so it maybe that sizing up eliminates this issue for those with powerful ‘cyclist’s legs’.
Verdict: Performance, comfort and style come together in a package thats fantastic value for money

Zone3 Aeroforce-X

- £295
With claims that the Aeroforce-X is the world’s fastest tri-suit, Zone3 has worked with Nopinz to produce a suit that aims to perform at a range of speeds for all abilities.
Using ‘golf ball technology’, dimpled sleeves and ‘Aerostripe’ sides, the suit’s designed to maximise aero gains, with lightweight panelling on the back to regulate temperature.
Our sample came up short in the upper body, leaving us feeling restricted around the neck, collarbone, and when on aerobars. While supportive, the chammy finished awkwardly on the leg inseam, causing rubbing against the saddle.
By contrast, the lower body fitted well, with the smooth, soft fabric offering core and leg compression and deep aero pockets providing storage for at least six gels.
The suit ticks many performance boxes, but with only five sizes available, taller athletes may need to look elsewhere.
Verdict: Lots to like and impressive tech, but for the price the chamois needs improving

Tenola Aspire

- £100
You may not have come across this tri-specific brand before. In fact, this is Tenola’s first outing in a 220 women’s test, but we did see them in our men’s reviews in 2019.
Made and designed in Great Britain by keen triathletes, we like the credentials of this brand. The Italian fabrics and cold-black treatment were nice to see during a heatwave in the testing period.
This suit did a reasonable job of keeping us cool, with mesh panels under the arms helping too, but we did prefer the more breathable fabric of the Airofin on balance.
Less positively, the design felt quite basic and old-fashioned, and the single-strip sticky leg grippers weren’t that comfy and started to peel away from the fabric early on in testing.
Two slanted rear pockets were adequate for an energy gel each, while the chammy was soft and comfortable, if a little bulky.
Verdict: needs a few improvements; feels overpriced for what’s on offer here

Huub Commit Long Course

- £119.99
The Commit is Huub’s new range of quality racewear offering value for money for novice triathletes. That said, we were impressed by the features on offer and the reasonable price point.
We’d happily pay an extra £20 over the Tenola suit here to get a more stylish design (that striking aqua blue on a women’s suit is a winner and looks great when on), as well as the lightweight fabrics that dried quicky and a 3D tri-specific pad that was silky and comfortable.
While it didn’t feel as cool as some others, the fabric felt smooth and nice quality, with a breathable mesh insert down the spine and lower back.
Two angled pockets with fold-over tops kept our gels safe. Our size small suit was a touch tight for this size UK10-12 tester, and we did find the leg grippers a touch unflattering, but that’s easily solved by sizing up.
Verdict: a stylish suit from a big brand that performs as well as it looks and is good value

Aptonia Long Distance

- £69.99
Aptonia is Decathlon’s tri brand and we were pleasantly surprised to see such an unusual design sitting at the budget-end of this year’s grouptest.
First impressions on the feel and quality were good. We liked the jacket-style suit, the choice of mesh around the arms and the breathable striped back panel, which kept us cool.
A few quirky touches included a pleat in the back for added movement across the shoulders. This was also the only suit on test to offer four pockets – two mesh on the lower back and one on each leg – allowing plenty of space to stash things for long races.
The chammy is a thin, stretchy gel pad which was quick to dry, but a touch more padding might be preferred for full Ironman distance.
Our only real niggle was the laser-cut hems on the shorts, which were a bit sharp on the edges, though those with slimmer thighs might find them okay.
Verdict: a striking suit with some nice features and the least expensive on test!

Santini Viper

- £159.99
Kudos to Santini for putting together a suit with a striking design, packed with extra features that the Italian brand claims are designed to help you achieve your ‘fastest bike performance ever’.
This is a bold claim, but we did like the feel of the fresh-touch Artico fabric and the ribbed aero panels on the arms. Overall, the fit on our size medium (size UK10-12 tester) was good, although it did feel a bit short in the body on the run, so we’d be tempted to size up, as is often the case with some of the more top-end ‘race fit’ brands.
The chammy was among the best on test, but although we understood the sentiment, we didn’t really get on with the large grippy area on the crotch, which is designed to help you stick to the bike.
For us, it seemed unnecessarily large and perhaps more suited to time triallists than to triathletes, as it felt odd to run in. Grab yours from Santini
Verdict: Some great features, but this tech-packed suit did feel quite bike-specific

Best vested tri-suits
There are still numerous cases for a vested tri-suit. Firstly, a vested tri-suit will often be cheaper than a sleeved version simply because there’s less of it – it’s easily possible to pick one up new for £50 or less by shopping around online or in specialist shops.
The next consideration is the extra restriction that some triathletes perceive to feel in a short-sleeved suit under a wetsuit.
Even now with super technical tri-suits that are purpose-built to cause minimal swim restriction, some fussy pros are still sceptical and opt to roll theirs down to the waist, before putting it on properly during the run through T1.
Dhb Aeron Sleeveless Tri Suit 2.0

- £115
Dhb’s Aeron range regularly punches above its fiscal weight, and the 2.0 proves very hard to fault in its tri capabilities. In the swim the fabrics bead water well, yet the two open rear pockets do cause some underwater drag.
The large mesh panels on the spine and sides are brilliant for breathability, a zipper garage minimises run-leg irritation, while the tacky leg grippers are as good as the lofty competition here.
Despite being billed as ‘suitable for long-distance triathlons’, it’s not something we’d personally want to spend circa 15hrs in due to the moderate pad (almost identical to the Zone3), but those with tougher bottoms and swifter speeds may find solace here.
The pockets can carry a buffet, however, and the suit is already reduced to £85 online, which ramps up the bargain appeal even further.
Verdict: High-quality and smart tri touches at a decent price; the aeron range has done it again

Assos Triator NS Speedsuit

- £330
This is the sleeveless version of Assos’ unique Triator SS Speedsuit (reviewed largely positively in issue 402). It loses the integrated ice pockets and, thankfully, the zip that extends worryingly close to the nether regions.
Elsewhere, Assos’s cycling heritage is evident in the supportive, low profile and run-friendly chamois that ticks the long-distance bike-leg boxes.
The highquality fabric beads water on the swim and the cut in the arms ensures a decent range of movement. It’s swift to dry on the bike and the textured material’s targeted at aerodynamics (not that we’ve seen any data).
The two rear pockets are fine for a gel each, but you’ll need a Bento box for more. The leg grippers are minimalist yet effective, but the lack of a zip garage is an odd omission given the mighty price tag.
Verdict: Innovaive and ready for Ironman, although the price and lack of zip garage limits appeal

2XU Light Speed Front Zip

- £150
As befits an Aussie brand, the Light Speed from 2XU would be my pick here for racing in the heat; the mix of lean materials, Coldblack treatment and perforated panels scoring the midsummer points.
Worth noting is that the chest front panel is seethrough, meaning nipples are on parade. The compressive properties seen in 2XU’s celebrated run tights is evident here in the thighs, although we think it’s time for 2XU to update the slightly-too-tight grippers of the long legs, especially when compared to Assos and Castelli’s contenders.
The small rear pockets, which just about house a small gel each, might not suggest so, but the comfy and cushioned pad, full-length zipper and breathability make this our long-distance pick. Yet the Light Speed will also be at home in any of the tri distances.
Verdict: The most versatile suit here for multi-distance racers, just be prepared to bare!

Castelli SD Team Race Suit

- £210
Planning for non-wetsuit sprint races? Then the SD Team, developed with the German Triathlon Federation, is the one for you.
Were it not for the chamois, it could almost double as a swimskin, with a hydrophobic treatment that beads water, no pockets to increase drag (meaning you’ll need a Bento on the bike for gels), and barely a seam to further disrupt the flow of water.
The cut of the arms ensures the maximum range of movement, even if you’ll need swimmer’s shoulders to pull off the look. And out of the water?
It dries swiftly, but it’s later in the bike leg where problems may arise, given the chamois lacks any serious padding – 20km is doable, 40km a push.
The effective, techy silicone grippers are the usual Castelli class, but you’ll need someone to do the suit up for you before you race.
Verdict: Superb on the swim, but lack of padding and pockets reduces longer bike ambitions

Aptonia Short-Distance Sleeveless Trisuit

- £29.99
Aptonia’s short-sleeved Short-Distance Trisuit impressed us last issue and it’s much the same with this wallet-friendly vested version.
Again, there’s a mesh strip along the spine for ventilation, a smart leg pocket for gels, a full-length zip guard, and a solid own-brand chamois that can handle short-course tri without proving bothersome on the run.
That’s the good stuff. We’d like some rear pockets for mid-ride and run fuel included while, understandably for the outlay, the material composition and finish quality of the stitching falls short compared to the rest here.
The elasticated grippers are adequate, and the legs come up quite short, while the other colour schemes on offer – navy/yellow and navy/light blue – are more attractive than this dated black/grey number.

Zone3 Aeroforce X Sleeveless

- £225
This is the sleeveless and short-course version of Zone3’s feted Aeroforce X tri-suit, a winning, wind-tunnel proven yet comfy contender for iron-distance racing.
The zip’s moved to the rear for non-wetsuit swim gains, while the hydrophobic material and slick covered pockets add to the aquatic appeal.
The textured and ribbed fabric has proven its credentials in 220’s own windtunnel tests, while the lean Elastic Interface pad will suit short-distance bottoms.
The laser-cut ends and tacky grippers of the lengthy legs continue the stellar theme, but a major flaw is that the suit’s nearly impossible to remove due to the zip head repeatedly catching in the full-length guard. Not ideal if you need a pre- or mid-race visit to the loo, and you certainly won’t want to rip it given the price tag.
Verdict: Hydrophobic, aero and comfy, but you may end p wearing it to work the next day!

Yonda Argento

£119£79
The ITU logo on the Argento Performance from British brand Yonda gives you a good idea of who it’s for; speedy triathletes who wouldn’t intend to use it for anything above Olympic distance triathlon, and possibly just sprint distance and below for non-elites.
Every second counts so there are no pockets to store snacks here, and the padding is just some thin fleecy material sewn onto the main fabric.
Made in Italy, the suit has Lycra Energy fabric from Cervico that promises UV protection, compression and stretch. Yonda also say the Teflon yarn coating makes this suit fast through the water, particularly useful for elites such as the Scottish national and GB paratriathletes who use it for non-wetsuit swims.
We can vouch for the stretchiness of the fabric, and it’s just as well because our size medium was very close-fitting on this tester and wasn’t quite as comfortable as the other suits on the run.
Flat seams increase comfort, but we found the heavy-duty reverse zipper was a little rough against the skin. The leg grippers are comfortable and fit well around the thighs, and we found the suit breathable on hard run and ride efforts.
Out of all the suits on test, the Argento Performance was indeed the fastest through the water in pool testing, saving us almost as much time as a swimskin would at around 2-3 secs per 100m consistently. For this reason, we can understand why the suit it popular with elites.

Huub’s new Raceline suit has plenty of impressive tech features that we’ve come to expect from the brand in recent years.
High-density chamois with drainage holes, wide leg grippers and two ergonomic pockets that are easy to grab from are some standout features, with lightweight Italian fabrics specced throughout.
Coldblack technology features on the main panels for moisture management, and there are flatlock seams to prevent chafing.
Billed as an aero suit, we found the Raceline offered a fairly relaxed fit, and the legs are on the shorter side, so don’t offer much coverage on the thighs.
The mesh back panel is also minimal, so there’s not much ventilation. But if you mainly race in the UK, that won’t be an issue.

New for 2021, the Activate+ tri-suits from Zone3 have a few upgrades on the entry-level Activate range. Tested here is the range’s Tropical Palm suit, which is aesthetically pleasing without being too loud.
For a medium it’s a relaxed fit, perhaps more relaxed than we expected considering we’re on the larger end of medium! So if you’re in between, check size guides and size down if necessary.
In terms of storage, there’s one rear pocket with room for a couple of gels, which makes the Activate+ less suitable for middle distance and above.
Zone3 have specced their Lycra sport fabric for most of the suit, with a thinner, breathable mesh panel on the back that kept us cool during hard efforts.

Dhb Moda Sleeveless Tri Suit

- £49
The Dhb Moda offers an impressive array of tri-specific features for such an affordable price-point. The Moda’s best suited for up to Olympic-distance events due to the relatively small rear pockets which can fit one to two gels.
The smooth polyester/ elastane body is comfy and we liked the back mesh panel to aid breathability. The ‘moderately compressive’ material did sag a bit on the swim and we needed extra support in the chest for run efforts, though the locking YKK zipper and the leg grippers felt secure.
Along with the Huub, the Moda could be a good pick for sunny racing thanks to its claimed UPF rating of 50+.
We like the Moda’s blue polka-dot colourway and style, and while its chamois is one of the thickest on test it didn’t get in the way when running.

Santini Ikaika

- £160
Fresh from Santini’s new collaboration with Ironman, the Ikaika suit’s designed for long-distance racing performance. It’s certainly one of our favourites designs on test, and the quality construction didn’t disappoint.
Our favourite feature is the ‘second skin look’ of the extra wide honeycomb leg grippers, which stay in place during all disciplines and aren’t too restrictive.
The large double rear pocket with ‘thermo-welded’ top side openings are a similar size to the Tri-Fit, but we found the high positioning a bit tricky to reach around and grab gels from on the run and bike.
Though the fit feels compressive and secure, as well as being fast-drying and feeling hydrodynamic in the water, comfort was affected by a slight down-pulling on the body.
As with most suits on test, those larger than an A cup will need to add their own extra support on the bust. It could be a good move to pair this with a sports bra as the chest part does become semi-transparent when damp.
Verdict: Professional-looking suit that’ll go the distance over an Ironman race

Huub Aura Triathlon Suit

- £139.99
The Aura is proof that simple but effective’s the way to go sometimes with trisuit design. It’s a good pick for racing in hot climes thanks to mesh panels across the lower and middle of the back, along with the ‘Coldback temperature management coating’ with UPF30 which aims to deflect heat and protect the skin from the sun.
The relatively thin but comfy, female-specific chamois and two envelope-style rear pockets that fit up to three gels each are suitable for distances up to half-iron at a push, but we’d want a little more padding for longer.
The 15cm leg inseam’s also the shortest on test (the Tri-fit’s the longest at 20cm), while the silicone leg grippers are comfy but not the most secure.
We felt the most comfortable and at ease in this classy black suit, the fit across the chest also providing just enough support for the run leg (on small busts).
Verdict: Smart and flattering design with features primed for hot racing conditions

Tri-Fit Evo Sleeveless

- £139
The only suit on test to have a split top and bottom design, the Tri-Fit Evo impressed with its well-thought-out features.
Silky smooth material gives way to an aero ribbed back panel which has two built-in, floating pockets that are very easy to access on the bike and run.
The suit performs well for all distances thanks to the substantial pocket capacity and added leg side mesh pockets – easily fitting around 10 gels in total.
The high-density foam chamois has an average thickness and doesn’t feel like an oversized nappy on the run, while also proving quick-drying post swim.
While we experienced no pulling thanks to the split design, we found the silicone leg bands cut into our skin somewhat and the zip garage to be a little scratchy.
Overall, it’s another good suit from Tri-Fit with a quality build, just falling a little short to be our number one.
Verdict: High-quality construction and features, just lacking slightly on comfort for our tester’s build

The only suit on test to be designed with a ‘double chest layer’, we were excited to try out this updated model from Zone3. Smooth water-repellent ‘Aquaflo’ fabric gives way to back and side mesh panels with two slim and discreet side pockets, which can house two gels each.
Best suited for short-distance, the female-specific ‘Tri-lite’ chamois provides decent padding around pressure points while the leg grippers don’t compromise circulation, actually turning out to be a little too baggy.
A big plus for us is the extra support around the bust area, which helped with comfort on the run leg. While the retro navy and coral colourway isn’t particularly flattering, it was the seams around the zip and chamois that resulted in some pretty extreme rubbing and irritation. Though we had no problems with the sleeved version.
Verdict: Affordable standard-distance suit option, shame the construction caused discomfort

Trimtex Drive Tri Skinsuit

- €179
With Trimtex’s bold claim that this suit has ‘a perfect ergonomic shape’, we had high hopes for the Drive Tri skinsuit, the most expensive suit on test.
First impressions were good, thanks to the practical mesh-panelled design and two roomy mesh back pockets. The material has a soft satiny feel, which in practice proved to be quick-drying and breathable.
The lock zip and zip garage are also good additions for comfort, but the high-rise neckline rubbed at the back, losing it precious points.
We were impressed by the rigorous sizing questionnaire on the website, yet felt the suit ran a little big for a ‘skinsuit’, which didn’t help the non-existent support in the chest.
The real winner here is the wide and über-comfy, laser-cut leg grippers, let down only by the Cytech chamois pad that though claiming to be seamless, felt scratchy on the stitching.
Verdict: Aero offering but lacks finishing details and comfort concerns around neckline

Tenola Inspire ITU Style

- £75
New British brand Tenola officially launched in 2018, with their range of affordably priced race suits, swimsuits and wetsuits.
Their ITU-style suit is primed for hot temperatures and claims to have UPF 50+ protection. The cut-out back mimics the classic swimsuit-style and the compressive material is very thin and breathable, supposedly treated to be water-, cream- and oil-resistant.
On the bike, padding is minimal though very breathable and the flatlock stitching reduced discomfort. On the flipside, we found the leg grippers to be too thin and there’s a distinct lack of pockets, which is at odds with Tenola’s claim that it’s suitable for six hours in the saddle.
The slightly oversized chamois becomes a little nappy-like on the run, which is a shame as we’d expect it to fit a little snugger in this area.
Verdict: primed for sprint triathlons in hot climates; shame about the baggy chammy

2XU Active

- £85
Aussie brand 2XU’s Active range comes up trumps with this affordable and quality tri-suit, the trendy ombre colourway and sleek mesh side-panelled design scoring extra points with us.
Three reasonably-sized, easily-accessible, elasticated back pockets are ideal for gel-stuffing. Along with a medium-sized hydrophobic chamois, comfort and fuelling is a clear priority, and we’d wear this suit for any and all distances.
Made from stretchy SBR SKIN LITE material, we liked the smooth feel but felt it lacked support for the muscles, not helped by the sizing running a little large despite our tester perfectly matching measurements for a size small.
Markedly, the Active has no support in the chest area, necessitating a sports bra to be worn underneath. The main drawback, though, is the narrowness of the leg grippers, lacking the comfort and style of a wider band.
Verdict: good quality for a great price, with plenty of fuel-storing options

Castelli Core SPR-OLY

- £110
Castelli’s recent foray into the tri market sees the launch of their cheapest suit, the Core. Despite the basic black colourway, this suit has a lot to offer.
Perfectly true to size, the Core is flattering and fits snug to the body thanks to the reduced seams and elasticated neck and arm holes.
Designed for short distances, the suit has a smooth-to-the-skin felt lining instead of a chamois pad and a quality-feel, lightweight fabric.
The long-line fit, meanwhile, flows down through the legs towards this test’s best silicone leg grippers. In terms of fuelling, there’s one roomy, envelope back pocket that Castelli claim will stay secure on the swim, though we found it difficult to access.
Unlike other suits on test, the Core’s zipper is located on the back with a long pull cord – worth bearing in mind if you like to unzip at the front when hot.
Verdict: high quality build with some nice touches for short-course racing

The best Ironman tri-suits
Triathlon brands are increasingly realising the aerodynamic benefits of tri-suits (remember that 80% of drag is caused by the rider, not the bike) and this collection of Lycra is the most tech-happy yet, with fabric boasting dimples, ribs and more all present and correct.
When choosing your Ironman tri-suit of choice, you’ll first need to decide what kind of Ironman athlete you are. Are aerodynamics worth the added costs that come with wind-tunnel, computational fluid dynamics (CFD) and velodrome action if it means scooping the age-group honours? Or do you just want something comfy and capable of carrying up to 17hrs worth of fuel to that unforgettable 226km (or 113km) finish-line experience?
Don’t compromise on your choice of tri-suit for Ironman. If it doesn’t fit properly, try another size. Try not to be influenced by a suit because it’s £25 cheaper or is better looking than the one that really works for you.
You’ll be spending many hours racing in your chosen suit of choice and something that bugs you on a 2hr brick session – hello rogue seam, dodgy zipper or soggy pad – will become a full-blown issue on your big iron day. That said, you’ll want to look and feel good in your Lycra armour of choice, so aesthetics does play a role.

Huub Anemoi II Sub22

- £299
Huub has pulled out all the stops with the Anemoi II suit. We tested the Sub22, which is for athletes expecting to ride at 22mph or below (the majority of the field at a long-distance race).
There’s also a Plus22 version with a few tweaks for those who race faster. Huub says the suit solves ‘Drag Crisis – also known as the Eiffel paradox, a phenomenon in which drag coefficient drops off suddenly as the Reynolds number increases’.
We have no idea either. But it’s fast. Very fast. Once you get it over your thighs, the fabric hugs, but isn’t intrusive. The chamois stood up to extended saddle time, while the run was comfortable.
Bonded seams promise a saving of four watts and two rear pockets are acceptable. Being Huub, the suit really comes into its own in the water thanks to the Arm Neutral technology, which is simply fantastic.
Verdict: A tremendous suit that offers compression and comfort in equal measure

Tri-Fit Geo

- £209
There’s a lot to like about the Geo and it’s clear loads of thought has gone into its design. Neat innovations like side-access rear pockets reduce drag but not storage, while the laser-cut hems give a supremely comfortable fit.
The star of the show, though, is the chamois, which is about as comfortable as you can get. The Tri-Fit team are considering upping the thickness beyond this model, widely used by their pros, but there’s no need.
It’s magnificent. Swim performance was solid and on the run the longer sleeves provided added sun protection. The fit wasn’t perfect around the arms and the colour scheme’s a little uninspiring, but that’s subjective.
The suit is is highly competitive in the mid-range price bracket, while the female version (not tested in this grouptest) equally impressed.
Verdict: Great value and built for saddle comfort; very ipressive all-rounder

2XU Aero Sleeved

- £130
2XU has an uncanny knack of producing quality kit at low prices and the brand has done it again here. At £130 this was the cheapest suit on test and, while it doesn’t have all the bells and whistles, it deserves consideration due to its value for money.
The seam-free sleeves and excellent fit ensure good aerodynamics and comfort in all three sports. They also promise advanced muscle support (unsubstantiated on this test).
The chamois is decent but not exceptional and the rear storage pockets are more generous than on many suits.
Having the top half only partially attached to the bottom means easy access for toilet stops, which is always welcome in a long-distance race.
The downside is that the fabric doesn’t feel as premium. It’s not a deal-breaker, but maybe this is the compromise for the highly competitive price point.
Verdict: A brilliant suit for those on a budget, but lacks the premium feel that others have on test

Santini Viper

- £179
Santini has made a suit that’s as flexible in its options as you could wish for. This long-distance version, worn by Ironman 70.3 world champion Gustav Iden, is the tip of the iceberg and even includes the option to customise upon request.
The basic suit has much going for it, not least the fact it looks great. The chamois is good, breathability is excellent and Santini promises superb sun protection.
Notably, there’s a unique grip around the crotch on the outside of the suit. It feels fine and looks superhero-esque, but it didn’t actually add much in terms of the promised extra saddle grip.
The longer sleeve fit was welcome and the longer length of the legs, whether intentional or not, was also nice. The major downside was the zip, which wasn’t all that comfortable and caused rubbing, particularly on the bike.
Verdict: Looks great, chamois does its job well and sleeves were a plus, but issues with the zip lets it down

2XU Compression

- £160
2XU won our Ironman tri-suits test in 2018 and 2019 with their Compression tri-suit, and little has been changed in
this version. The compressive legs give it a USP, while the full-length zip with garage, spongy pad and lean fabric are still present to heighten long-course appeal.
As evidenced by the internal flatlock seams, the suit ticks most boxes for a long-course race day, but there’s just a sense that, while the other brands are pressing forward in their creations, 2XU are now standing still with this suit (although we’ve warmed to the 1980s aesthetics in the year we’ve had it).
Our Silverstone wind-tunnel testing with the Bike Tailor in 2020 saw it come sixth out of 10 overall at the 0° and 5° yaw angles, probably explained by the suit costing half the price of those aero tested to their limits.
Verdict: The broadest appeal and cheapest here, but we want an upgrade

Santini Audax

- £240
As evidenced in the striking M-Dot branding, Santini are an official Ironman sponsor. We’ve previously struggled with the sheer size of Santini’s cycling-esque pads on the run, but that’s been rectified, thanks to a slimmer, iron-specific pad with gel inserts.
It’s a lightweight, lean and breathable suit, with easy-to-access open rear pockets (which sadly won’t persuade any non-wetsuit swimming friends), high-quality grippers and, for us, the Japanese-influenced designs have the best looks on test.
And the aero appeal? There’s a smart zipper garage but it doesn’t open out for any pre/mid-race toilet stops, meaning we’re more likely to use this for 70.3.
Verdict: Stylish and sleek, but costly and unconvincing in the wind tunnel

Huub Anemoi+

- £299.99
The Anemoi+ arrived in 2019 with road-tested changes from the original Anemoi design. The first is the longer zip that makes it suitable for a stand-up wee, and lengthier legs, ribbed arms and bonded seams to increase the aero appeal.
We used the Anemoi+ on a 3.8km/120km/11km DIY tri in Hawaii in ’19. The arms were unrestrictive on the sea swim, the chamois barely there on the run, yet with just enough seated comfort on both the tri-bars and hoods.
It was the new Moov&Cool tech – combined with the underarm venting – that really stood out, and at no point did the garment chafe, itch, allow sunburn or feel laden with sweat.
As a mid/back-of-the-pack athlete who stuffs their pockets with gels, we require more than the tiny solo pocket for racing longer than 70.3. But for triathletes at the pointy end? The Anemoi+ is a mighty contender.
Verdict: Most impressive, but for the speedsters over the completers

Zone3 Lava Long Distance

- £195
After years of not quite making the top-end tri-suit grade, Zone3 blew us away in 2020 with their Aeroforce speedsuit (from £275) both in the wind tunnel and on the road.
Much of that painstaking R&D (with input from aero specialists Nopinz) has trickled down into the sub-£200 Lava – and it feels like they delivered the sweet spot between affordability (all things are relative), aerodynamic pursuits and practicality.
Lengthy ribbed sleeves, a full-length zip and supportive Cytech pad add to this winning performance vs practicality ratio.
We were struggling to find faults until we reached for the pockets, which are small, shallow and difficult to access on the move (we wouldn’t trust sizeable OTE gels in them), and, while the pocket’s cover at the top wins swim points, it made stuffing empty gel packets back into them tricky, especially on the bike.
Verdict: Aero, more affordable and just oh-so close to being faultless

Castelli PR Speed Suit

- £300
Probably due to not hitting the lunchtime curry stall, lockdown has left us feeling leaner than we have since beer first tickled our taste buds. And yet the PR Speed Suit still felt furiously tight as we peeled it on. Once in place, as evidenced by Cam Wurf breaking the Kona bike course record in this, the suit provides the aero goods, while feeling unrestrictive.
‘Second skin’ is an overused term, but the ultra-lean material genuinely feels like it’s painted onto the body – there are no wrinkles to be found and the ribbed arms and lengthy sleeves add to the drag-cheating package.
The 17cm-wide pad and sizeable duo of rear pockets are iron friendly, although for £300 we’d want fully flatlock seams inside.
Onto the run and the pad stays problem-free, although the aesthetics were slightly ruined by our hairy chests being visible through the fabric.
Verdict: Smooth, slick and sleek, and the design makes this a classy – if pricey – contender

Dhb Aeron Lab

- £190
Hailed as a second skin, the Aeron Lab feels ultralight and ultra-sleek. The closefit design, combined with aero-disruptive fabric on the arms, shoulders and legs, aims to provide maximum speed for minimal effort on the bike.
The suit offers complete flexibility with the neckline and grippers seamlessly blending into the body to enhance freedom of movement.
However, at 5ft8in, we wouldn’t have wanted to be any taller, so sizing up may be required for longer bodies. Three big rear pockets offered generous storage and the chamois pad kept us comfortable all day on test.
On initial wear, the internal seams were irritating to the skin, but these softened in time and didn’t provide any further issues. It’s worth noting the legs are shorter than others on test, which may or may not be to your taste.
Verdict: Compression supports lacking, but this is a light, flexible and stylish suit

Van Rysel LD Trisuit

- £59.99
Decathlon’s visually-appealing design is perfect for those operating on a budget. The lightweight, breathable fabric offers plenty of flexibility with a soft neckline to ensure all-day comfort, though the light colour around the chest area means wearing a bra is a must!
Although lacking the aero features of some pricier models, the femalespecific design adapts and stretches around the natural curves of the female body, giving freedom of movement in all disciplines.
Storage options were great, with a deep pocket on each leg and a further two on the back, allowing plenty of capacity for even the longest events.
The slimline chamois was perfect for the swim and run but felt a bit too narrow for our wide-nosed saddle. However, our main criticism was the stiffness of the leg and arm grippers, which both started to irritate by the end of testing.
Verdict: At this price point it’s a great entry-level option with unbeatable storage capacity

2XU Light Speed Trisuit

- £150
Bucking the long-sleeve trend, 2XU’s sleeveless tri-suit targets heat control and muscle stabilisation. The UV protective fabric claims to reduce heat absorption from the sun, improve airflow by almost 200% and provide enhanced aerodynamics.
In testing it felt lightweight and breathable, aided by the open-cut under arms and neckline, giving the feeling of freedom even during the hottest session.
Targeted compression claims to dissipate load transfer on the knee while running which, in practice, made our quads feel well-supported. The chamois felt stiff at first but proved comfy through all our cycling and gave us no issues on the run.
The two rear pockets were disappointingly small, though, and we found the split front design cut in on our stomach and pulled up when standing, so taller athletes may want to size up to accommodate this.
Verdict: Poor storage, but provides decent freedom and flexibility to get on with your race

Trimtex Aero 3.0

- €359
Kristian Blummenfelt wore the men’s version of the Aero 3.0 when he went 3:25:21 at 70.3 Bahrain in 2019, so we know they’re built for speed.
The women’s Aero 3.0 is bursting with aero enhancements tailored to each part of the body, such as the fabric which includes dimpled mesh around the arms and shoulders and ribbed panels on the legs.
There’s clearly no compromise on quality, with the quick-drying, breathable material offering flexibility and a specially adapted chamois providing multidiscipline comfort.
Wide leg grippers prevent unwanted movement and the split front design allows extra movement during the run and swim.
Two rear pockets are also deep enough to hold fuel for all-day racing. Trimtex advises it’s an extreme fit and to size up, but if anything our sample felt roomy, so ideally try before you buy.
Verdict: It’s a hefty price tag bu the suit oozes quality and may help shave ooff those precious seconds

The Lava range has been around since 2013 and it’s easy to see why it’s been a hit. It not only looks stylish but packs in plenty of performance-enhancing features.
Drag-reducing Aero-Stripe arms offer enhanced aerodynamics, while the balanced compression in the legs provides muscle support to help improve endurance and stamina.
The Aeroforce Soft-Touch fabric gives a touch of luxury, with that barelythere feeling offering flexibility and breathability, all while providing 50+ UPF protection.
Comfort is also taken care of with the women’s specific pad providing targeted pressure point relief on the bike while remaining unobtrusive during the swim and run.
A close fit and 360° stretch means no compromise in movement and plenty of freedom around the hips and waist. We could wear this all day.

Yonda Ombre Racesuit

£139£89
Hailed as a premier long-distance suit, the Ombre’s breathable fabric offers full flexibility throughout the shoulders, with ribbed sleeves enhancing speed through both air and water.
The neckline sits close to the skin without being restrictive and the wide leg grippers prevent excess movement. The chamois offers comfort and support, though the rear pockets are on the small side.
The suit offers UV40 protection, although the coloured segments do become transparent when stretching into the TT position, not helped by the suit’s tightness around the hips and thighs.
Yonda advises due to the compressive fabric, you should size up but, even using their height and weight guide, their sizing was a mystery.

Part of Zoot’s new Elite range, this suit sets the standard in performance and comfort. The compressive fabric claims to increase circulation and muscular support.

The chamois pad offers excellent shock absorption and particular comfort in the TT position. A trio of rear pockets delivers plentiful storage and easy access.
The premium Italian fabrics offer UV50+ sun protection and, although we’d like a splash of colour, this is a tri-suit that performs on every level.
