The Castelli Endurance 3 Bibknicks are designed for all types of rides, from commuting to Gran Fondos. They feature the Progetto X2 Air Seamless Seat Pad, offering exceptional comfort with its two-piece construction. This includes a seamless SkinCare layer that adapts to your body’s shape and a perforated cushioning layer for added comfort. The anatomic cut and lie-flat GIRO3 leg grippers, along with a soft elastic waist, ensure the shorts stay in place. The Endurance Evolution fabric supports muscles and keeps moisture levels low, making these bibknicks ideal for any ride length.
