  • 35 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 loft and thermal efficiency
  • 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 performing 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
