You'll be well-rested tomorrow.

Loaded with premium, high-loft 800-fill down, the Marmot Couloir 0-Degree Down Sleeping Bag will keep you sleeping comfortably in your tent or bivy though a harsh winter storm. Thanks to a DWR-coated nylon shell, the Couloir fights off that frost and condensation that go hand in hand with winter camping and mountaineering.


  • Premium 800-fill goose down compresses well, rebounds nicely after repeated compression, and features a high warmth-to-weight ratio
  • Water-repellent, windproof, downproof nylon microfiber shell delivers lightweight performance without buckling under the pressure of alpine expeditions
  • Down-filled draft collar, full-length draft tube, and ground-level seams help prevent leaks and improve warmth retention
  • Stretch tricot baffles allow the bag to be stuffed and unstuffed without creating a tear in the baffle material
  • Nautilus 6 baffle hood surrounds your head with warmth; Face Muff allows you to cinch hood tight without irritating your face
  • Classic trapezoidal foot box gives your toes plenty of room to wiggle; heater-pocket in foot box lets you pack in some additional warmth
  • Stuff and storage sacks included
  • EN comfort-rated at 12-degrees F for winter and shoulder-season warmth; lower limit rated at -2 degrees F for occasional use in colder winter conditions
  • Item #MAR1127
