For our longest rides where a comfortable kit keeps us going, we put on the Castelli Endurance 3 Bib Short to ensure we finish our ride as strong as we started. The bike-specific anatomic cut offers a perfect fit in riding position, while the Endurance Evolution fabric provides excellent muscle support and quick-drying properties. For greater long-distance comfort, the Progetto X2 Air Seamless seat pad keeps our perineal area padded for long days in the saddle.
