The Castelli Espresso 2 Cap is simple, well-made and does its job well. At £27, it isn’t cheap, but the quality is there to back up the price and there’s a huge range of colours on offer.
Cycling caps are one of those bits of kit that don’t get much attention but make a real difference on warm days. They keep the sun off your head, stop sweat running into your eyes and allow you to get on with the ride.
If you’re follically challenged, especially, they also prevent the world’s most insane tan lines. (Personally, I’m not – but I ride with a couple of people who are.)



The cap is made from a performance mesh, which makes it genuinely breathable under a helmet. I never felt particularly uncomfortable, even on longer climbs where heat tends to build up.
Sweat wicking is quick and effective and it carries a UPF 50 sun protection rating.
At 22g the Espresso 2 is barely noticeable on the head, and the fit is secure under a helmet without bunching or riding up. The peak is short enough to flip up easily when you don’t need it, which is exactly how a cycling cap should work.

The cap comes in a range of colours to match the rest of the Espresso kit range, so if you’ve already gone for the Espresso jersey and socks, it’s an easy way to pull the whole look together, if you like that kind of thing. If not, it’s useful for being able to match/complement other kit too.
The construction feels durable and it has washed well without losing its shape or fading.
We’ve previously tested the GripGrab Summer Cycling Cap, which is similarly heat-focused. It doesn’t have the same breadth of choice of colours, but it does come in £9 cheaper.
You could also look at Swrve’s four panel cycling cap, which is a little more casual and less warm weather focused and has an RRP of £19.50.
At £27, the Castelli Espresso 2 Cap is on the steep side for a thin mesh cap, and there are cheaper options that do a broadly similar job. But the quality is evident throughout and once you’ve worn it a few times, it becomes the cap you reach for without thinking.
