The Pro Mesh Long Sleeve Base Layer has been developed to provide a breathable layer for use on intense inter-season rides. Delivering extra coverage over the arms, this Base Layer provides improved protection on chill rides. Woven in one complete piece, the Pro Mesh Long Sleeve Base Layer avoids seaming, meaning it sits superbly under jerseys and jackets without causing irritation. Fast wicking, it helps keep you in optimal condition to perform on early and late season rides.
