When winter blows in, we bypass the indoor trainer and pull on the Sorpasso RoS Bib Tight for long hours in wet, cold conditions. Built with Castelli's fleecy nanotech fabric, this cozy pair repels water yet remains highly breathable, while the reinforced thighs and upper front offer extra wind protection and warmth where we need it most. As the miles get longer, the perforated, seamless chamois keeps us comfortable in the saddle.
