  • Features

    • Mountain Equipment's Good Night's Sleep rating for this bag is -9°F
    • The Good Night's Sleep temperature rating is based on laboratory and cold-chamber testing, plus extensive experience manufacturing sleeping bags for use in extreme conditions
    • GORE-TEX® INFINIUM™ 10-denier outer shell is durable but light, exceptionally breathable and highly protective against snow and the effects of condensation
    • GORE-TEX INFINIUM 10-denier inner footbox and hood lining
    • 29 oz. of 800-fill-power goose down with a minimum down/feather ratio of 90/10 is sourced from a traceable and Down Codex® approved small-scale European supply chain
    • Expedition fit with EXL® system is both roomier and has improved thermal efficiency
    • EXL® technology minimizes dead airspace around the body and pulls fabric away from the down, allowing it to loft fully
    • With a more generous fit that is longer and wider, it affords greater comfort when used for long periods of time; additional clothing can be worn or stored within the bag
    • Vertically aligned V-baffles on the chest and foot piece; 14:7cm trapezoid baffles throughout all other parts of the bag
    • Ground-level side seams provide maximum thermal efficiency by increasing the surface volume of the top-half and ensuring sidewalls can wrap uninterrupted around the main body
    • 7-baffle, low-volume anatomically shaped hood provides exceptional down control for long-lasting insulation
    • The DC7 LV hood minimizes weight, has less deformation when cinched down small and offers single-handed closure easy-run drawcords
    • 6-baffle anatomically shaped footbox features BullsEye™ technology and offset Sharks Toe™ foot construction to maximize thermal efficiency
    • Full-length Gemini™ zip baffle and integrated collar with Lode Lock™ closure
    • The Lode Lock system with its low profile auto-locating closure combines all the advantages of a magnetic fastener with those of a mechanical lock
    • Its one-handed, quick-release closure uses 2 captivated internal magnets to draw the locking mechanism together and ensure that once connected it cannot be accidentally opened
    • Inner pocket keeps essentials warm and dry
    • Includes waterproof roll-top stuff sack and storage cube
    • Certified to the Down Codex® standard, which promotes transparency and animal welfare in the down supply chain
    • Mountain Equipment is a member of Fair Wear Foundation, a European initiative working to improve workplace conditions in the garment and textile industry
