From Himalayan basecamps to Polar research tents, the Glacier Expedition offers extreme warmth and comfort in some of the coldest conditions on Earth.

Using 1352g of minimum 700-fill power DOWN CODEX-approved duck down and a lightweight and water resistant 30-denier DRILITE® LOFT™ outer fabric with recycled face, the Glacier Expedition is both exceptionally warm and able to withstand heavy use on long and demanding trips.

Trapezoid baffles across the top of the bag ensure optimal loft, reduce cold spots and prevent down migration. In contrast, at the foot of the bag, a six-baffle system focuses warmth around your feet—essential when spending extended time in dangerously cold climates. In the hood, a five-baffle system ensures the down is optimally distributed for warmth and protection over long-term use.

Inside the bag, our time-tested EXL® elasticated stitching system minimises dead airspace, reduces drafts, and pulls the liner fabric away from the down, allowing it to loft effectively for maximum warmth. Meanwhile, a full-length Gemini™ entry zip baffle eliminates heat loss in this vulnerable area and is stiffened so it won’t catch in the zip. The low-profile magnetic Lode Lock™ closure and collar drawcords are effective and easy to use in the dark.

Our Glacier Expedition bag has a roomy Expedition fit for comfortable sleeping on long trips and accommodating extra clothing when necessary.

With a Good Night’s Sleep Temperature of -35oC (31oF), the Glacier Expedition is an ideal bag for polar conditions and high-altitude expeditions.
