Castelli Endurance 4 Bib Shorts
Built with Endurance Evolution fabric, the Castelli Endurance 4 Bib Shorts provide optimal muscle support while ensuring you stay drier in a wide range of conditions. The anatomic cut delivers a perfect on-bike fit, allowing the shorts to move seamlessly with your body as you ride. To help regulate temperature on long climbs or warm days, the mesh bib straps and back panel increase breathability and keep heat build-up to a minimum.
For unmatched long-ride comfort, the Endurance 4 Bibs feature finishing touches like the GIRO3 leg grippers, which lie flat and stay securely in place, ensuring a smooth, irritation-free feel. If you want bib shorts that combine cushioning, cooling and consistent performance, the Endurance 4 are the upgrade your long-distance epic rides deserve.

About Castelli
At the front since 1876.
Castelli has been at the front of cycling apparel since 1876, founded in Milan as the original maker of pro race kit. From the first cycling jerseys to today's WorldTour-proven aero garments, the brand has spent nearly 150 years putting innovation onto the backs of the fastest riders in the world.
Castelli outfitted the first organised cycling teams in Italy and has been a constant presence in the pro peloton ever since. The Scorpion logo appears on more WorldTour podiums than almost any other apparel mark.
