Free feeling and aerodynamic. The Castelli Free women’s tri singlet keeps you cool with the SpeedFreak ventilated front fabric and Velocity mesh on the back, while also reducing your aero drag. A SnapLock fastener makes connecting to shorts super easy and prevents the shorts riding up while swimming or cycling.
The FreeAero pockets are convenient for spare nutrients and the soft-finish armholes reduce chaffing, both giving those extra little touches that count.
