Marmot is an outdoor recreation clothing and sporting goods company founded in 1974 as "Marmot Mountain Works". The company was founded in Grand Junction, Colorado by local resident Tom Boyce and two University of California, Santa Cruz students, David Huntley and Eric Reynolds, who shared the common goal of making their own mountaineering equipment. Two years prior to the founding of Marmot, Boyce secured an order for the climbing apparel used in the film The Eiger Sanction starring Clint Eastwood, and Huntley made the original prototype gear that Boyce was using on the Wolper Productions/National Geographic documentary Journey to the Outer Limits, about the Colorado Outward Bound School. It was during this documentary production that cameraman Mike Hoover, who later worked on Eiger Sanction, saw the equipment that Boyce was using during the portion filmed in Peru. Just prior to Christmas 1973, Mike Hoover called Boyce and placed the order that led to the formation of the company in Grand Junction.
After Jarden was acquired by Newell Rubbermaid in 2016, Marmot was spun off from K2 and K2 Sports was sold to Kohlberg & Company in 2017. Marmot stayed with Newell.
