How we test

At road.cc 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 road.cc scores mean

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

Castelli's Core Mesh Sleeveless base layer might raise an eyebrow from the other half when you pull it on, but the open mesh fabric ensures it keeps you cool and dry on hot days when rides can be ruined by base layers that just can't cope with the sweat.

It's available in short sleeve and sleeveless versions. I have found the sleeveless version is more comfortable with tight-fitting short sleeve jerseys; there's less material to bunch up. As with just about all Castelli clothing, it's on the small side (I tested a medium) but the stretch of the fabric means it's not restrictive at all.

In constructing the Core Mesh base layer, Castelli have paid careful attention to minimising seams, and this manifests itself in absolutely no chafing.

The neck has a soft fabric lining, with a small Castelli scorpion on the neck and red stripe on the left shoulder. They've cut it long as well so there's plenty of overlap when tucked into bib shorts.

Working temperature

Castelli reckon it's good for between 20 and 30°C. UK temperatures have only recently risen into the lower working temperature range, where I can confirm the base layer lives up to the high expectations I had for it. I've been using it happily well below the minimum stated temperature range; anything from 10°C up has proved to be just fine.

And on those hot days, the base layer never becomes heavily saturated with sweat, so you stay dry even when riding hard. The open mesh just lets sweat moisture pass cleanly through to the next layer to be evaporated away.

The Castelli's Core Mesh Sleeveless base layer works exceptionally well on the bike, and the best thing is that it doesn't even cost that much. Look at the road.cc base layer review archive (road.cc/review-archive?tid=9739), it's clear that £30 is about average for a high quality base layer. If you're looking for a comfortable and hard-working summer base layer, this is a very good candidate for your money.

Verdict

A comfortable sweat-wicking base layer ideal for hot days.

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

This is the perfect minimalist piece to keep you cool in warm weather. The fully open mesh serves mainly to hold the jersey off the skin, creating a layer of air between your skin and the jersey to help you maintain a constant body temperature. The fabric absorbs practically no moisture, and it weighs next to nothing so it won't weigh you down.

Quality piece of kit. Been using it now for a couple of months. It's the one bit of kit the wife seems to like me wearing 3

True. I ask you, is this any way for a middle-aged man to make a living?

Without doubt, the most homoerotic product photo I've ever seen on road.cc! Problem is, Mrs withnails sees this photo and questions why I have such skinny arms: this cyclist clearly doesn't...thanks, road.cc
