The Marmot Expedition Mitt provides uncompromising warmth in a waterproof design. Water-repelling PrimaLoft® Gold synthetic insulation provides warmth and protection without adding bulk. Waterproof and breathable Marmot MemBrain® inserts ensure you have protection from the elements while moisture-wicking DriClime® Bi-component lining keeps hands dry. Taffeta at the beginning of the mitts means snow can't cling and the gauntlet drawcord helps to keep out any persistent precipitation.
