Polartec Power Stretch Fabric Polartec Power Stretch fabrics feature comfortably snug four-way stretch, and are very breathable, keeping you dry when you sweat and providing warmth without weight. The material features proprietary construction with two unique surfaces. The durable nylon outer layer is wind- and abrasion-resistant, while the soft inner layer pulls moisture away from your skin. Compression stretch can improve performance and reduce the chance of certain types of stop-go injuries. Polartec Power Stretch keeps skin dry through three complementary mechanisms: The fabric is highly breathable and does not restrict movement of moisture vapor "Touch Points" on the fabric inner surface draw off sweat, which is wicked off the skin to the outside of the fabric When sweat reaches the outside of the fabric, it spreads out to many times its original surface area, enabling it to dry at least two times faster than cotton Lifetime Warranty Marmot products include a limited lifetime manufacturer's warranty against defects in materials and workmanship. About Marmot In April 1971, University of California Santa Cruz students Eric Reynolds and Dave Huntley were in Alaska on the Juneau ice fields for a Glaciology school project. This was where the idea of Marmot, originally a collegiate climbing club, began. Reynolds and Huntley soon began making prototypes of down products such as vests and sleeping bags in their dorm room in Santa Cruz. By the spring of 1973, Reynolds and Huntley partnered with fellow climber Tom Boyce to open a modest rental and retail location, named Marmot Mountain Works, in a 100-year-old building in Grand Junction, Colorado. Their first large order was for 108, as the producer called them, "very puffy jackets" for the movie The Eiger Sanction, with Clint Eastwood, which helped make down outerwear fashionable. In 1976, Marmot was one of the first companies to recognize the value of a new technology being developed by W.L. Gore & Associates. Marmot was soon producing waterproof Gore-Tex sleeping bags, with Reynolds and Huntley testing early prototypes by sleeping in meat lockers and under fire sprinklers, and later introduced the waterproof/breathable fabric into nearly all Marmot products. From humble beginnings, Marmot and its product line have grown over the years, and today the company is headquartered in Rohnert Park, California, with offices all over the world and distribution in more than 60 countries.
