For optimal performance on our winter rides, we kit up with the Castelli Raddoppia 3 Jacket. Built with GORE-TEX INFINIUM WINDSTOPPER materials and backed by sweat-wicking, heat-trapping fleece, this cold-weather layer dulls sharp gusts and icy temps to help us go the distance, while the lighter weight side panels boost mobility and breathability, ensuring we don't overheat on climbs. Through flurries and drizzles, the treated material brushes off flakes and droplets to keep us dry, and the drop-tail hem protects us from spray.
