At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Chapeau! Mesh Base Layer Short Sleeve is light, comfortable and ideal for hot rides (or turbo sessions) as it's great at wicking away sweat to keep you cool. It's well made and pretty stylish too, should you be 'forced' to unzip, though it could be just a tiny bit longer in the body.

I wear a base layer on every ride no matter how hot, cold, wet or slow, and that means the Chapeau! has seen plenty of use. To be honest, most of the time I've completely forgotten about it too... and that's a good thing!

I've been impressed with it from the off. It's suitably close fitting without feeling restrictive, helped by the stretchy side panels. Even under the most aero of jerseys there's no bunching of fabric, and it feels comfortable against the skin.

The mesh is made from two different ratios of elastane and polyester which, crucially, wick sweat really well. It's super fast drying and surprisingly strong given how light and see-through it is. Its transparency means that I wouldn't use it by itself for spin classes, but for home turbo sessions it's perfect.

The arms are quite short, which I'm a fan of as there's no risk of poking out of jersey sleeves, plus there's a sleeveless version for a fiver less if that's more up your street. The only area I'd like improved is the length of the body; however, I have a relatively long torso for my height (it's not me in the pics), and you may find it fine.

A benefit of a shorter body is the lack of unsightly seams under your bib shorts, although as there's no heavy hem it's unlikely to show anyway. All the other seams are flatlocked, so no irritation there.

I like the lack of labels. Labels in base layers really irritate me: so much effort (I hope) goes in to making the thing comfortable, and then somebody staples in 100 labels with (I swear) purposefully sharpened corners. Here, washing instructions are printed inside a side panel – other manufacturers take note!

At £34.99 it's priced sensibly given the impressive performance and fit, and matches the Castelli Pro Issue SS Base Layer. If you're not too concerned about aesthetics, cheaper alternatives such as the Lusso Race Base Mesh (£24.99) score highly and could save you a few quid.

If this sky blue doesn't match your kit, Chapeau! also does it in white, grey, navy blue or black.

The Chapeau! Mesh Base Layer Short Sleeve is perfect for hot rides of any kind, as it wicks so well and dries very quickly. The quality is high and fit is excellent – barring, perhaps, the ever-so-slightly short torso – so it creates that feeling we all love; namely, the feeling it's not even there to start with.

No bunching, comfortable seams and no labels.

Very well indeed.

Tell us what you particularly liked about the product

Fits well, looks great.

Tell us what you particularly disliked about the product

Tiny bit too short.

How does the price compare to that of similar products in the market, including ones recently tested on

It's at the cheaper end of the market, though there are cheaper available (if only typically by around £10). At £35 it's the same price as the Castelli Pro Issue SS and dhb Aeron Equinox, but £10 more than the similar Lusso Race Base Mesh. It's not hard to spend £50+ on very similar base layers to the Chapeau! though.

Did you enjoy using the product? Yes

Would you consider buying the product? Yes

Would you recommend the product to a friend? Yes

Use this box to explain your overall score

I think the Chapeau! hits the sweet spot for performance and style, but it's just short of exceptional as you can get cheaper – and ideally it'd be just a little longer in the body. It's very good, though, and an eight.

Overall rating: 8/10
