Mountain Equipment Glacier Expedition Women's Sleeping Bag

The Glacier Expedition provides extreme warmth and comfort, making it a top choice for harsh environments like Himalayan basecamps and Polar regions.

Filled with 1352g of minimum 700-fill power DOWN CODEX-approved duck down and protected by a water-resistant 30D DRILITE® LOFT™ outer fabric, this bag is built to endure tough, long-term use while keeping you exceptionally warm.

Trapezoid baffles on the upper portion of the bag prevent cold spots and down migration. At the same time, the six-baffle foot system focuses warmth around your feet—crucial for surviving dangerously cold climates. A five-baffle system in the hood ensures even warmth and protection over extended use.

The EXL® elasticated stitching system minimises dead airspace, reduces drafts, and allows the down to loft for maximum warmth. A full-length Gemini™ entry zip baffle blocks heat loss, and the stiffened baffle prevents snagging. The low-profile magnetic Lode Lock™ closure and collar drawcords are simple, even in the dark.

Designed with an Expedition fit, this sleeping bag offers plenty of room for a comfortable night’s sleep and allows for extra layers when needed.

Rated for temperatures as low as -35°C (31°F), the Glacier Expedition is the perfect choice for polar conditions and high-altitude adventures.

Temperature ratings

For our Expedition bags, we don't give Comfort, Limit, or Extreme limits, as the ISO 23537 test excludes the testing of “extreme climate zone expedition” sleeping bags or bags with a measured limit temperature colder than -24 °C.
