Mountain Equipment

Combining high-quality down, technical expedition-proven construction elements and a durable water resistant outer fabric, the Mountain Equipment Glacier 450 is an extremely versatile bag ideal for all-round mountaineering, trekking and climbing expeditions where nighttime temperatures dip below freezing.

The 450g of minimum 700 fill power DOWN CODEX-approved duck down offers excellent warmth for minimal weight, while the lightweight and water resistant 30-denier DRILITE® LOFT™ outer fabric with recycled face copes with condensation and snow, ensuring a dry and comfortable night’s sleep whether in a tent or snow cave.

Trapezoid baffles across the top of the bag ensure optimal loft, reduce cold spots and prevent down migration, while at the foot of the bag a six-baffle system focuses warmth around your feet—an essential in sub-freezing conditions. In the hood, a five-baffle system ensures the down is optimally distributed for warmth and protection over long-term use.

Inside the bag, the time-tested EXL® elasticated stitching system minimizes dead airspace, reduces drafts, and pulls the liner fabric away from the down, allowing it to loft effectively for maximal warmth. Meanwhile, a full-length Gemini™ entry zip baffle practically 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.

Based on a tapered Alpine fit to maximize thermal performance while minimizing weight and with a Good Night’s Sleep Temperature of -9C (16F), the Glacier 450 is ideally suited to summer alpinism and general mountaineering, as well as lower-altitude trekking, backpacking and camping.
