The updated Free Speed 2 Race Top offers the flexibility of a two-piece with the aerodynamic advantages of a one-piece tri suit. Elbow-length sleeves and a next-to-skin fit reduce drag when we're on the bike, where our upper body provides the greatest resistance to forward motion. With all the time spent in the sun and heat training, the Free Speed Top uses a UV-blocking fabric on the back of the jersey to protect from the sun's rays and keep you cooler. Castelli's SnapLock fasteners at the lower back attach the jersey to their Free Tri Short to prevent it from riding up, and the Giro3 elastic gripper further secures the jersey in place.
