Gravel and off-road riding often mean somewhat slower speeds and more variability, so we can ride in cooler conditions before putting on a full jacket. This jersey was made to provide a high level of warmth, especially at lower wind speeds, to give that perfect balance of warmth without overheating. Style-wise, it's influenced more by outdoor than pro racing, but Castelli's DNA is still there for the on-bike performance, sacrificing only aerodynamics. All-road features include the higher-volume pockets as well as the zippered chest pocket so you don't lose valuables. This jersey is excellent as a layering piece under an Unlimited Puffy Vest or an Aria Vest.
