Tackle those long base mile rides in the Endurance 3 Short from Castelli. The short is designed to offer superior comfort for the entire duration of your ride so you can focus on the route and not your attire. Made of Castelli's Endurance Evolution fabric, the short stays in place with a compressive fit to help support muscles, and wicks moisture away quickly. Further muscle support comes courtesy of textured compression side panels. Castelli builds the Endurance 3 with its top-tier Progetto X2 Air Seamless chamois that's redesigned to increase breathability and comfort. It sits softly against the skin, with a bacteriostatic layer and four-way stretch in the two-layer design. Castelli also includes its lie-flat Giro3 leg grippers to keep the leg openings in place for a soft, not sticky, feel against the skin. Final details include the embossed Castelli wordmark on the legs that add a touch of elegance.
