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

The 465 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.

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—an essential in sub-zero 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, 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 maximal 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.

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