For mild winters in the mountains, continue to enjoy your bike and the surrounding passes with the Mortirolo 6S. Designed by Castelli, this cycling jacket for men features Gore-Tex Infinium™ Windstopper® technology to maintain your body temperature, insulate you from the cold, and also wick away moisture to prevent overheating. With its loose fit, you can also wear this jacket in colder temperatures by layering a baselayer or a long-sleeve jersey underneath.
