When training outside year round is a must, we need protection from the elements, so we trust in the Castelli Alpha Doppio RoS Jacket to keep us dry and comfortable for miles on miles. The GORE-TEX INFINIUM WINDSTOPPER 150 fabric construction blocks out wind and rain, while the Polartec Alpha Direct insulating layer keeps us warm without overheating.
