The Castelli Endurance X2 Short starts, perhaps unsurprisingly, with the Progetto X2 Chamois. This is Castelli's top-line, three-layer pad designed to support your sit bones and resist chafing, no matter how long the ride. Sewn around the X2 are eight panels, two of Action PowerLycra for abrasion resistance in the seat area, and the remainder of Energia LycraPower, which is designed to support your muscles with a lightly compressive fit.
