To enjoy your spring and autumn bike training sets, you’ll need a breathable jacket that deflects wind and rain – and hopefully looks alright in the pub. Matt Baird, Jacqui Davies and Kelly Stokes test 13

Unless you live in a particularly warm and dry climate, a cycling jacket is a practical addition to your triathlon kit.

Acting as a convenient outer layer, it should provide valuable protection from the elements while being light and thin enough to be stashed in a pocket.

Ideally, it should be a trusty layering piece you can quickly put on during transition or on a training ride, either as a final addition or under a gilet

How to find the best cycling jacket for you

As there are a great many cycling jackets out there for both men and women, it can be tricky to decide which one to buy. 

Firstly, you should think about whether to prioritise windproofing or waterproofing. While waterproof jackets help stop the rain getting in, they tend to be less breathable than a lightweight windproof option, which should have enough ventilation to let out any sweat.

In general, it’s best to look out for cycling jackets with a high collar and insulated chest, but ventilation across the back and underarm areas. 

Also, you’ll want to make sure you invest in a lightweight, easily packable cycling jacket that has space to store any energy gels or bars you take on the road. 

We also like cycling jackets with a ‘dropped tail’, as it covers your lower back while leaning forward. And look out for a high-quality zip with a large pull so you can find it easily when wearing cycling gloves

Before you make your final decision, don’t overlook the importance of colour. Making sure you’re easily visible to other road users is a vital safety precaution, so we recommend opting for a bright, reflective cycling jacket.

If you want something more substantial than the light and packable options listed here, take a look at our list of the best winter bike jackets.

Best men’s cycling jackets

Santini Guard Nimbus

"Santini

‘Dark clouds’ is the Latin translation of Nimbus and it’s on rainy days in circa 10°C temperatures where this Santini shines.

Easily stashable into a cycling jersey’s rear pocket, this 128g jacket’s water protection comes courtesy of a double layer fabric.

The seams – not just taped but ‘thermo-welded’ – help prevent precipitation penetration and overall the Nimbus’ fabric can withstand light rain showers (downpours will eventually triumph).

Bonus points are added for the waterproof sleeve cuffs, although the tail isn’t as long as some. The single zipper pocket is easy to access and will hold a phone and fuel, while the fit feels the most aerodynamic.

There’s an element of windproofing, while reflective details aid visibility (or buy the orange version).

Verdict: Not cheap, but a techy wonder for winds and light rain.
