Castelli Endurance 4 Bib Shorts

The heart of this short is Castelli's renowned top-of-the-line Progetto X2 Air Seamless seat pad, expertly combined with a classic short design. But comfort doesn't stop there, every detail has been meticulously refined to support you on your longest endurance rides.

A great pad is only effective when paired with a perfect fit. That's why Castelli has carefully placed seams around the hips to ensure an ergonomic, bike-ready shape. The Endurance Evolution fabric feels soft against the skin while offering excellent compression and superior moisture management. Everything stays securely in place thanks to the incredibly comfortable GIRO3 leg grippers.

This short is built to provide lasting comfort mile after mile.
