Castelli Endurance X2 Bib
Castelli have engineered everything in this short to make your longest rides just a little bit more comfortable. Everything Castelli does is geared toward speed, and they know that means doing some long rides. They stay with the proven comfort of their Progetto X2 Air seat pad, use new Endurance Evolution fabric for muscle support, and give the short a perfect eight-panel anatomic fit and their Giro3 leg gripper. Of particular note is the bib construction, which they’ve engineered to accommodate those cyclists whose long rides are primarily to burn calories.
