Windbreak Jacket (plain) 5-15° Performance Jacket for training and racing in cold weather conditions. The front and upwind points of the jacket are made of three layers of composite windbreak fabric to create better weather protection. The jacket is weather-resistant with a durable waterproof DWR coating and has a fitted tailoring that comfortably fits the riding position at high speed. The more open and breathable fabric on the back can effectively dissipate heat when riding with high intensity.
