The Endurance 3 knicks bring Castelli's long-distance comfort to a classic waist-style short. The Progetto X2 Air Seamless pad is paired with a soft, compressive fabric that manages moisture and feels dry in most conditions.
A soft elastic waist lies flat without binding, and an anatomic cut with seams placed around the hip gives a natural shape on the bike.
