Hot days leave us wanting a jersey that adapts for the heat by providing a sleeveless fit and outstanding breathability and that's just the start of what the Entrata VI Sleeveless Jersey has to offer. It's designed with Castelli's pro racing technology to make for an all-around performance jersey that's ideal for racing training and casual riding. AirMesh fabric wraps around the shoulders and side panels for extra stretch and an airy feel and three standard rear pockets leave room for essential items and snacks.
