Castelli Insider W Sleeveless

THE indoor top for Zwift, Peloton & Co. ... or for use in the gym - and stay pleasantly cool.

We designed this sleeveless top to cool more than if you weren't wearing a top at all. It works because it spreads sweat over a larger area, promoting evaporative cooling. Of course, it won't make your indoor sessions sweat-free, but it will very much make them more comfortable. It's deliberately kept simple and cut close to the body, with a back pocket. We equip it with the HEIQ Fresh Tech finish, which naturally prevents odours from building up in the garment over time.

Lightweight, quick-drying 3D mesh material (93% polyester, 7% elastane) for optimal sweat management.
