Marmot was founded in 1974 by Eric and Dave, two climbers who worked as ski instructors and guides at the same time as they began to develop and manufacture their products. Their first big order came from Universal Studios, who needed 108 pieces of "Very Puffy Jackets" for a film shoot with Clint Eastwood (The Eiger Sanction). No problem, they replied, and spent the next week sewing "Very Puffy Jackets", a jacket that later became the bestseller "Golden Mantle". In 1976, a collaboration with W.L. Gore which resulted in bivy bags, down sleeping bags, jackets and tents with GoreTex-coated outer fabrics. Marmot is today W.L. Gore's oldest outdoor customer. A lot has happened since then, and Marmot's know-how and ability to find durable, waterproof and durable materials has made their products popular with both professional adventurers and the common man who simply appreciates high quality that can be trusted.
