Duofold is performance based outdoor apparel that gives you the freedom to focus on your outdoor passion. Duofold uses the latest fabric and garment technology to give you rugged protection against the elements while keeping a popular outdoor look so you can concentrate on the job at hand. Duofold began its tradition of innovation in 1906 and has since continued that tradition with the introduction of the first two-layer thermals, the Varitherm performance base layer, and the Duo-Dri moisture management system. Duofold's two-layer technology features soft cotton close to your skin and a wool outer layer for warmth giving you the best of both worlds. With quality trusted by the U.S. Military, National Ski Patrol, and American Association of Snowboard Instructors, whatever activity you choose and whatever the weather-Duofold has you covered.
