Castelli Superleggera

Since 2011, Castelli has pushed the boundaries of lightweight construction in bib shorts while focusing on durability. They have analyzed what truly matters: the shorts must securely hold the seat pad in place with minimal fabric use, but of course, without becoming transparent. They need to withstand at least a full season of hard (race) use. Therefore, Castelli has developed an entirely new material, a fabric that saves 30% in weight compared to knitted options while providing the same support and opacity.

Castelli collaborated with the world's leading factory to create a gradient fabric that becomes lighter as the length of the leg increases, with the final piece weighing just 90 g/m² compared to standard short fabric, which weighs about 220 g/m². This fabric is incredibly light yet maintains adequate durability and excellent abrasion resistance, at least against the saddle. Note that while the shorts save only 48 grams when dry, they also absorb about 30% less moisture when sweating. So, when you’re sweating your way up Alpe d'Huez, you could save up to 150 grams.

These shorts make no compromises on comfort. They feature the top Progetto X2 Air Seamless seat pad, the spectacularly striped mesh bib from the Free Aero Race 4 Bibshort, and a flat, elastic woven leg gripper to keep everything in place.

Highlights: Elastic gradient material, up to 50% lighter with improved durability, minimalist bib construction made from mesh strips, integrated leg grippers with external Lycra, embossed logos, heat transfer scorpion logo, Progetto X2 Air Seamless seat pad.
