The previous GT Winter Jacket was virtually perfect; however, in winter cycling, the stakes are too high to ever accept virtually perfect, so we continued to refine the formula for the S11 EVO generation. The evolved GT Winter Jacket S11 features an updated fir pattern for more versatile comfort in upright cycling positions and less constriction across the chest and shoulders. New additions of the RX thermal textile down the side panels, under the arms, and around the collar increase breathability to maintain a dry microclimate – critical for enduring winter base miles. Returning tech includes the redoubtable AIRBLOCK-EVO.916, a breathable, stormproof softshell that shields your body’s leading edge against wind, rain, and frigid winter air alike, and it’s joined by the ultra-elastic AIRBLOCK-EVO.888 on the sleeves. A rear panel of highly insulating RX EVO Plus presents a thermoregulating, water-repellent face to the elements, protecting your back and your pockets from precipitation and road spray alike.
