Castelli Endurance 4 2026 men's short cycling shorts

Designed to help you rack up the miles with ease, these Castelli bib shorts prioritise long-lasting comfort above all else. Their Endurance Evolution fabric provides excellent muscle support whilst keeping you comfortable and dry, whatever the conditions. The cut naturally follows the riding position, with no pressure points.

The mesh straps and back promote ventilation to keep you cool during exercise, whilst the Progetto X2 Air Seamless chamois provides remarkable comfort and improved airflow, even on the longest rides. The GIRO3 thigh bands provide effective support, lying flat against the skin without feeling tight.
