Chapeau! Mesh SL Base Layer Exe Blue Striped



Smart looking baselayer that does the job for sensible money

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.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

  • Exceptional
  • Excellent
  • Very Good

  • Appalling

Not everyone wears them, but I reckon a good quality baselayer is one of the most important parts of a cyclist's wardrobe no matter what the weather, and the Chapeau Mesh SL Base Layer is such a thing. It's not the best I've worn but it does offer a great balance of quality, comfort, performance and price.

  • Pros: Well priced, lightweight, good wicking
  • Cons: Material isn't the softest I've worn

For warm weather riding I prefer to choose one of the many mesh style baselayers I have in my collection as they just feel much lighter on and nice and airy.

The Chapeau feels exactly that, especially when paired with a lightweight summer jersey. On descents you can feel the air blow through, removing the heat from your body, most noticeable after a long, hard, sweltering climb.

In such conditions the Mesh SL draws moisture away from your body, mostly without getting massively overwhelmed; if it does, it soon dries out in the breeze as soon as your speed picks up.

Both the front and rear panels use the mesh material and it's plenty comfortable enough, though not as soft and pleasurable against the skin as Lusso's Race Base Mesh Layer.


The sides are made from a smooth fabric and these extra panels give the Mesh SL a nice defined fit. Sizing is spot on to Chapeau's chart, with this medium fitting me closely, avoiding any wrinkles or bunching under a jersey.

A clever touch is the use of the fabric from the side panels over the top of the shoulders, preventing the compression from bib short straps from irritating by rubbing against mesh.


With an rrp of £24.99 it's pretty much in the ball park for a lot of the baselayers we've tested recently. The Lusso I mentioned above is the same price and the excellent Pearl Izumi Transfer Sleeveless is just a fiver more. Five quid the other way will get you one of dhb's Blok Mesh Sleeveless baselayers for £20.

The Chapeau looks and feels to be well made and I gave it some really good stretches to test the thin mesh fabric without managing to tear it or pop any of the seams.

There are a good range of sizes from S to XL and four colour options: white with Exe Blue logo or Exe Blue stripes like we've got here, or the same in Hot Pink.

Tell us what the product is for

Chapeau says, "Our new summer base layers are quite simply, very good. They look superb and do what they should do, which is help regulate your body temperature as the mercury rises. Available in short sleeve or sleeveless options, they are also very handy as a top to wear when training indoors."

Tell us some more about the technical aspects of the product?

Chapeau says, "The main kite mesh pattern fabric is made in Italy and takes on the task of moving moisture away from your skin quickly whilst the soft touch side panels allow for a bit more flexibility of fit. A base layer should of course be quite fitted but the addition of side panels increases the comfort as well as adding to the aesthetics."

As part of the Tech Hub here at F-At Digital, our senior product reviewer Stu uses the knowledge gained from putting well over a 1,000 products through their paces (including hundreds of bikes) to write in-depth reviews of a huge range of kit. After first throwing his leg over a race bike back in 2000, Stu's ridden more than 160,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him he still likes to smash the pedals rather than take things easy. Although, as he spends a fair bit of his time reviewing ebikes these days he's becoming an expert in letting the motor take the strain. He's also waiting for 23mm race tyres to make a comeback!
