Product description
Get some shut-eye in the death zone with a little help from the Marmot CWM EQ -40 Degree Down Sleeping Bag. This 800-fill goose-down-insulated bag is built for the coldest, harshest weather on the planet - from the South Col to the South Pole. Its waterproof breathable MemBrain fabric prevents rogue bits of water from clumping your down and affecting your chances of summiting and getting home safely.
  • MemBrain 2L waterproof fabric helps shelter the down insulation from external condensation, snow, and water
  • MemBrain 2L fabric is also highly breathable so evaporating sweat won't condense inside the bag and cause the down insulation to clump
  • Premium 800+-fill goose down packs down well, rebounds nicely after repeated compression, and features a high warmth-to-weight ratio for ultra-cold nights
  • Nautilus 6-Baffle Hood and down-filled collar seal you up against the cold that kills quickly, without a face full of drawcords
  • Reinforced Thermo-Pane footbox gives you more goose down so you come home with all your toes
  • Oversized, down-filled draft tube along the zipper ensures no cold air gets in
  • Hidden draft tube pocket means you dont have to unzip your bag and surrender your bubble of warmth to find your watch
  • Numerous stretch tricot baffles keep the CWM EQs shape and insulation in place for years of expeditions on every continent
  • Baffles on chest and feet sections run vertically so that rolling around won't shift the down
  • Stuff and storage sack are included
