Castelli Superleggera Bib Shorts Black

Light, Cool and Straight Out of the Future
Castelli examined what the short really needs to do: it needs to hold the seat pad securely in place while otherwise adding as little weight or fabric as absolutely necessary (without being transparent, obviously), and it needs to last a season of hard use. So, they engineered a brand-new fabric using a woven rather than a knit that shaves 30% in weight for the same level of support and non-transparency. Then Castelli worked with the world's leading mill to construct a gradient fabric that becomes increasingly lighter the farther down the leg it extends, with the last part weighing a mere 90 g/m2 compared to normal short fabric, which weighs around 220 g/m2.

Performance Plus
This fabric, while being insanely light, maintains a decent durability along with excellent abrasion resistance, at least against the saddle. Castelli don't guarantee it against unplanned slides across the asphalt, so please keep the rubber side down! This short doesn't compromise on comfort, they use Castelli's top Progetto X2 Air Seamless seat pad, the spectacular striped mesh bibs from the Free Aero Race 4 Bibshort and a flat stretch woven leg gripper to keep everything in place.
