Castelli Mortirolo 6S Jacket - Men's Dark Gray/Silver Gray/Red Reflex, M

For mild winter riding, the Castelli Mortirolo 6S Jacket is our top choice for an insulated outer layer that keeps us warm without overheating. Its GORE-TEX INFINIUM WINDSTOPPER fabric combines with a fleece liner on the upper chest and sleeve front to block out cold wind, while its warmer material on the back is designed to let heat and moisture escape.
