Castelli Endurance 3 Men's Cycling Shorts provide endurance-level comfort for every ride with Castelli's most comfortable seat pad. The main story of this short is the use of the renowned top-of-the-line Progetto X2 Air Seamless seat pad in an otherwise traditional short, but in fact every little detail has been obsessed over to ensure your comfort on your next long endurance ride. A great pad is useless without great fit. The seams are placed around the hip area to create a perfect shape on the bike. The Endurance Evolution fabric has a soft hand while providing excellent compression and moisture management. And it's all held in place with the amazingly comfortable GIRO3 leg gripper. This short offers exceptional value and is ready to deliver lasting comfort on your longest rides.
