Description

Endurance-Level Comfort for Every Ride

The Castelli Men's Endurance 4 Short combines a top-tier Progetto X2 Air Seamless seat pad, supportive Endurance Evolution fabric, and secure GIRO3 leg grippers to deliver a highly comfortable, well‑fitting short for long endurance rides.

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 they've 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. Delivering exceptional value, this short is built to provide lasting comfort mile after mile.

Features:

  • Endurance Evolution fabric provides optimum muscle support and feels drier in nearly all conditions
  • Anatomic cut for perfect on-bike fit
  • Progetto X2 Air Seamless seat pad for even greater comfort and improved airflow
  • GIRO3 leg grippers lie flat
  • Fit: Tailored
  • Weight: 177 g

Way Too Small

Unfortunately I was unable to evaluate the quality or comfort of these shorts. I wear 36 waist pants and by the sizing chart, I ordered the XL. I was unable to put them all the way on so they are being returned. They were so small I really don't know what size I would need now so will probably not reorder them. I have worn other brands and the XL has always fit me. That being said, quality looked good and it had a nice chamois. Disappointed in this as they are available at a nice price.
