Hip packs, bumbags, fanny packs… whatever you call them, they’re now one of the most popular ways of staying hydrated and storing kit on rides. For example, if you take off your sunglasses and want to keep them safe.
Love them or loathe them, hip packs are a way to ditch your backpack on MTB rides and provide somewhere safe to store your best mountain bike sunglasses when not wearing them.
Here are our favourites in terms of price, practicality and comfort.

EVOC Hip Pack Pro 3l
!["Best]("https://images.immediate.co.uk/production/volatile/sites/21/2019/07/best-Hydration-Packs-05-fa8c07b.jpg?quality=90&resize=620%2C413" "\"Best")

The Evoc Hip Pack Pro’s good-sized main pocket is backed up with plenty of well-considered stash and sleeve pockets, giving excellent carrying and organisation capacity.
It has a bladder holder and two bottle holsters, which are easy to use on the bike. The back panel is well formed, supportive and breathable.
Combined with the broad, stretchy wings and strap, this makes the EVOC exceptionally comfy. Materials and construction are top-notch.
It’s expensive considering it doesn’t come with a reservoir (EVOC’s own 1.5l hip pack bladder costs £29.99 separately). The top zip could do with being a little bit longer for easier access.

There is a lot to like about the slim, minimal design of the Bontrager Rapid Pack. Two zipped pockets with internal mesh compartments offer plenty of easily accessible storage, with a space between them for a standard bottle.
The large foam back panel holds the bag in place securely and the waist strap doesn’t have any flappy loose ends.
With just 1.4 litres of storage, you can only pack the bare essentials. No bottle is supplied and the tight fit of the bottle holder makes it difficult to slide your drink back into place while riding. The back panel can also get quite sweaty.

Lowe Alpine Lightflite Hydro

- Price: £28
- Weight: 258g
The Lowe Alpine Lightflite Hydro bag offers four litres of storage, which is enough for racing and even longer days in the saddle if you pack light.
There are two exterior mesh pockets, in which you can stash smaller items, such as energy gels and multi-tools, within easy reach. The bag comes with a 500ml bottle, and the slightly angled bottle holder makes it easy to grab on the go.
It’s by far the cheapest bag here and for the price it’s hard to find much to fault.
It’s not a bike-specific pack and its less figure-hugging shape means it tends to move around a little when fully loaded, though.

Osprey Seral 4
!["Male]("https://images.immediate.co.uk/production/volatile/sites/21/2020/09/OSprey-Seral-4-7da99e2.jpg?quality=90&resize=620%2C413" "\"OSprey")
- Price: £60
- Weight: 300g
With its wide wings, the Osprey 4l Seral feels comfortable and secure even when carrying 1.5l of water plus kit. The waist clip is easy to use, even with a pair of the best mountain bike gloves on.
Thick back padding prevents anything in the large single pocket from digging in. It’s not too sweaty, either. Capacity is decent, even with a full reservoir.
Build quality meets Osprey’s high standards. A handy magnetic clip holds the hose in place.
The hose doesn’t release from the bladder for easy refilling. It’d also be better if it were held in a separate pocket, rather than an internal sleeve. We missed having exterior stash pockets for trail snacks.

Also consider
The following packs scored fewer than four stars, but are still worth considering.
CamelBak Podium Flow Belt
!["Male]("https://images.immediate.co.uk/production/volatile/sites/21/2020/09/Camelbak-Podium-Flow-Belt-fdca370.jpg?quality=90&resize=619%2C413" "\"Camelbak")
- Price: £45
- Weight: 181g
The Camelback Podium Flow Belt’s 2-litre volume is just big enough for ride essentials, with useful internal organisation plus a slim, zipped external pocket for your phone or keys.
We found the padded back and not-too-wide strap comfortable, and neither bulky nor sweaty. CamelBak’s excellent Dirt Series 620ml bottle with mud cover is included.
Replacing the bottle while riding is tricky. Your pump has to sit diagonally, taking up more space and limiting its length (to around 20cm). The waist clip needs a good squeeze to open, which is fiddly with thicker gloves on.

Dakine Hotlaps 2l
!["Best]("https://images.immediate.co.uk/production/volatile/sites/21/2019/07/best-Hydration-Packs-03-b2fee81.jpg?quality=90&resize=620%2C413" "\"Best")
- Price: £30 (+ water bottle) / $40
- Weight: 199g (no bottle)
Dakine’s Hotlaps is simple and lightweight, and sits comfortably against your back. The waist strap holds it securely in place, but it doesn’t quite match the stability of Mavic’s Crossride.
With a 2-litre volume, there’s space for spares and snacks. The main compartment features a fleece-lined pocket and a couple of extra compartments to organise your gear. There’s a foldaway bottle holder on the side. It’s well priced too.
This is the only pack here that doesn’t include a water bottle or bladder, and we found it hard to reinsert a bottle when riding. It’s also the least breathable of all the options we tested.

Mavic Crossride Belt
!["Best]("https://images.immediate.co.uk/production/volatile/sites/21/2019/07/best-Hydration-Packs-06-c884fda.jpg?quality=90&resize=620%2C413" "\"Best")
- Price: £62 / $55 / AU$NA
- Weight: 310g
With its triangular shape, the Mavic Crossride Belt is very stable. The 600ml bottle is easy to access (if you’re right-handed) and stays securely in its pouch.
There’s enough space for a tube, multi-tool and tyre levers, or a few snacks. The dedicated pump pocket is handy too. We like the elasticated waist strap, and the tabs can be tucked away neatly.
Breathability is okay, but not great. For the limited capacity it offers (don’t expect to take anything more than the bare necessities) it seems a little over-engineered.

Source Hipster
!["Best]("https://images.immediate.co.uk/production/volatile/sites/21/2019/03/six-of-best-bum-bags-cource-03-1513337689976-1de6w1ygtizfq-21900e3.jpg?quality=90&crop=47px%2C0px%2C1351px%2C900px&resize=620%2C413" "\"Best")
- Price: £69
- Weight: 465g
The Source Hipster’s removable harness (not pictured) does an excellent job of reducing movement, making it the most secure pack here.
The single-sided strap adjustment keeps the loose end tucked away, and there are bungee cords for a jacket, and the hose for the 1.5-litre reservoir is insulated.
Without the harness, the pack slumps a little. There’s no support from the back panel and no side straps to pull the weight in, so it bulges away from your back when loaded, which makes it move around more. Also, the three front pockets are very small.

Thule Rail 2
!["Male]("https://images.immediate.co.uk/production/volatile/sites/21/2020/09/Thule-Rail-2-1047aa6.jpg?quality=90&resize=620%2C413" "\"Thule")
- Price: £60
- Weight: 230g
Decent dimensions make the Thule Rail’s two litres of storage more generous than it sounds, so we rarely struggled to carry all we needed for a longer ride, including a larger pump.
It’s comfy to wear, thanks to its stretchy wings and belt. Construction quality feels premium.
We like the mesh stash pockets and soft-lined phone pocket. Bright internal fabric and dividers make it easy to find small items.
While there’s room for two bottles, none are included. Replacing them is difficult when on the bike.
The narrow waist strap means the pack isn’t as stable on rough tracks when fully loaded as others here. Its storage isn’t that flexible either.

Osprey Seral 7
!["Best]("https://images.immediate.co.uk/production/volatile/sites/21/2019/07/best-Hydration-Packs-07-0433b61.jpg?quality=90&resize=619%2C413" "\"Best")
- Price: £70 / $86 / AU$113
- Weight: 532g
The Osprey Seral 7 is one of the comfiest and most secure packs here, despite its 7-litre capacity. The 1.5-litre bladder is big enough for longer rides, with a mouthpiece that provides plenty of water with each gulp, and its magnetic connector is easy to find when riding.
There’s ample space for tools, plus two decent-sized pockets on the waist strap. Four compression straps enable you to tighten things down to keep the contents secure.
The waist straps can’t be tucked away, so they hang loose. It’s not the most breathable pack because it sits so close to your back.
