About this product
What Is the Castelli Endurance 4 Bibshort?
The Castelli Endurance 4 Bibshort is built around Castelli's top-of-the-line Progetto X2 Air Seamless seat pad, which Castelli calls its most comfortable seat pad. The pad has a seamless, bacteriostatic skin care layer that adapts to the shape of your body and saddle without folds, and a cushioning layer with Seamless Integrated Technology (S.I.T.) and a perforated viscous comfort zone. Castelli placed the seams around the hips to give the short an ergonomic, bike-ready shape.
The body is made from Endurance Evolution fabric, which feels soft against the skin while offering excellent compression and superior moisture management. Mesh bib straps and back keep you cooler, and the GIRO3 leg grippers lie flat. Castelli rates it for 59 to 95°F (15 to 35°C) and gives it a Tailored fit.
