This interesting piece of kit from Castelli is intended to keep you cool while training or racing thanks to its Prosecco Ice fabric construction, a material that’s designed to actively cool your body by transferring heat and sweat away from your skin.

The design of grey jumbled Castelli letters all over the fabric disappears when the material is at work, so you know when it’s doing its job.

Fit is close and comfortable and we really did feel the difference with the vest on – it kept us much cooler and dryer than we were expecting despite the provocation of sun, hill climbs and a thick jersey on top.

We would actually consider swapping the top of a two-piece tri suit for this, especially given its UPF 50+ sun protection.
