Stay warm on cold-weather climbing, backpacking and mountaineering trips with this feature-packed Marmot Couloir 800-fill goose down bag.

  • High-loft 800-fill-power goose down gives you unsurpassed warmth for remarkably little weight--packs down tight, too!
  • Water-repellent, windproof, downproof nylon microfiber shell is ultra-lightweight, yet strong; Sarcophagus Shape™ increases comfort
  • Nautilus 6-baffle hood envelopes your head in warmth, while the Face Muff allows hood to be cinched snug without digging into your face
  • Down-insulated draft collar and draft tube backing the full-length zipper seal cold out; zipper guards prevent zipper snags
  • Draft collar features easy-access drawcord; locking, two-way zipper prevents bag from inadvertently opening during the night
  • Hidden two-way draft tube pocket inverts into draft tube; holds watch or small essential items you need in the night
  • Spacious Nautilus footbox allows down to loft fully around your feet for optimum warmth
  • Ground-level side seams eliminate cold air leaks
  • Baffles are made with stretch tricot, providing strength and long-wearing durability
  • Includes nylon stuff sack and cotton storage sack

Marmot constructs each bag with attention to detail and each 800-fill power goose down bag is inspected to ensure the highest quality possible.
