Warm-weather rides call for a jersey that won't hold us back. The Castelli R-A/D Jersey is a lightweight and aerodynamic jersey trusted by the Herd for its comfort and performance features. Featuring Castelli's Air_O Stretch fabric, the R-A/D Jersey moves with us as we ride, wicks moisture from our body, and keeps us cool on hot days. The triple rear pockets design allows us to keep our snacks and water close by, and the elastic hem ensures the jersey isn't going to ride up when we are climbing.
