Long distance made easy-or easier

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


  • Endurance Evolution fabric gives optimum muscle support and feels dryer in nearly all conditions
  • Newly engineered bib strap construction is comfortable on a wide range of body shapes
  • New improved Progetto X2 Air seat pad for even greater comfort
  • Giro3 leg grippers lie flat
  • Rear reflective tabs
  • Heat transfer logos
