The Endurance 3 Cycling Bib Shorts elevates traditional cycling shorts to a whole new level of long-ride comfort. Starting with the fabric, this is Castelli’s Endurance Evolution material. Incredibly soft against the skin, it’s also excellent at dealing quickly with moisture while also providing your hard-working muscles with compressive support. At the end of the legs, the renowned GIRO³ leg grippers hold the shorts beautifully in place.

When it comes to the fit, Castelli always excels. The Endurance 3s are no different. Seams are carefully placed around the hips to create the perfect fit on the bike. And the careful tailoring ensures you’ll enjoy excellent freedom of movement as you pedal. Mesh bib straps to the upper body hold the shorts in place and allow for improved airflow and breathability. 

Progetto X2 Air Seat Pad

Inside the shorts, you’ll find Castelli’s premier Progetto X2 Air seat pad. This exceptional seat pad has an incredibly soft and seamless upper face material, delivering superb comfort. The next layer, Castelli’s infinitely variable thickness padding, imparts just the right level of support where you need it, thicker under the sit bones and thinner on the sides and under the perineum. The results are intense comfort with reduced bulk.
