dhb Aeron Body Map Sleeveless Baselayer

Sleeveless baselayers work well with thin summer jerseys to keep you happy on cooler rides, and dhb's Aeron Body Map Sleeveless Baselayer does a great job with a good fit, thoughtful design and a soft, warm feel.

• Pros: Good fit, warm, wicks well
• Cons: Relatively thick and heavy, may be too long for some

The Aeron is knitted as a tube, so the only seams are at the edges, despite it incorporating three different fabric types. The 'panels' are strategically placed according to how much the various areas of your torso sweat, dhb says, with a lumpy 'Tuck Knit' in the sweatiest.

These lie in a large cross over your chest, plus over your upper back and beneath your armpits. It's tricky to say how effective they are over 'regular' weaves, though unzipping (and exposing the chest) does provide rapid cooling. Another clue is that, post-ride, the Aeron was damp but never soaking. The fabric is relatively chunky, but wicks well.

I used it mainly for mild/cool rides down to around 12°C, under thin summer jerseys, but even with temperatures in the mid teens I never felt like I'd boil over. It's probably too warm for days when the sun might come out properly, though. It's on the thicker (and heavier) side for a baselayer.

The lower third gets a micro rib knit for a 'light compression' effect, though this didn't feel any different from the rest to me. The fit all over is bodyhugging without being tight or restrictive, and with no movement, bunching or even labels, comfort is high. It's soft against the skin, too.

The only niggle is the generous length, especially at the front – the seams can show as obvious lines through your shorts, and you may find it reaching your lap. I found it OK but borderline, despite being quite long in the torso.

It comes in four sizes, from S to XL, but just this one colour (a white option could be useful). You're not spoiled for choice elsewhere, of course, with dhb itself producing a high-scoring contender with the Blok Mesh Sleeveless Baselayer. It's lighter, cheaper and features a dropped tail.

For less heat (and thickness) the Pearl Izumi Transfer scores very highly at £30, while if it's looks you're after, then Alé's recently tested £35 Intimo Velo Active impressed as much with its style as its performance.

The dhb Aeron Body Map Sleeveless Baselayer is a no-nonsense choice that's comfortable, usefully warm and well made, and it enjoys near-constant discounting on Wiggle's website – it's currently available at £15. Stocky riders may not get on with it, but taller figures will find it a versatile, pleasing and useful bit of kit.

Verdict

Relatively warm and thick with a slim performance fit; it's very comfortable, though length may be an issue
