MemBrain fabric is waterproof, breathable fabric with excellent durability. It reduces internal condensation and the chilling effect caused by condensation build-up, and -- when used with insulated garments or sleeping bags -- protects the insulation from harsh weather conditions.
Marmot M-series Fabric
Designed for moving light and fast, Marmot's M-series materials combine stretchy, water-repellant, abrasion-resistant, breathable shell material with an insulating buffer layer for versatile warmth. M2 shells offer a balance between weather resistance, breathability, and thermal protection, and are appropriate for a wide range of aerobic use in moderate to cold conditions.
Marmot products include a limited lifetime manufacturer's warranty against defects in materials and workmanship.
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.
