Mountain Equipment Glacier 450 Women's Sleeping Bag (-8°C/18°F)

A superb all-round bag for general mountaineering and lower altitude trekking trips. With a tapered Alpine fit, this protective bag is ideal for those looking to reduce weight without compromising on warmth. Combining high-quality down, technical expedition-proven construction elements and a durable, water-resistant outer fabric, the Glacier 450 Women's is a highly versatile bag ideal for mountaineering, trekking and climbing expeditions where nighttime temperatures dip below freezing. The 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 to ensure a dry and comfortable night's sleep. Trapezoid baffles across the top of the bag ensure optimal loft, reduce cold spots and prevent down migration. At the foot of the bag, a six-baffle system focuses warmth around your feet, 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, the time-tested EXL elasticated stitching system minimises dead airspace, reduces draughts and pulls the liner fabric away from the down, allowing it to loft effectively for maximum warmth. A full-length Gemini entry zip baffle eliminates heat loss in this vulnerable area and is stiffened so it will not catch in the zip. The low-profile magnetic Lode Lock closure and collar drawcords are effective and easy to use in the dark.
