Mountain Equipment Glacier 450 Sleeping Bag (-9°C/16°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 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.

Care Instructions

Technology

	Down Codex Since 2009, the DOWN CODEX programme has set high ethical standards for down sourcing, eliminating live-plucking and force-feeding, and ensuring only top-quality virgin down is used, certified to the Responsible Down Standard (RDS). A multi-award-winning certification scheme grounded in comprehensive and transparent auditing that ensures full traceability and quality.
	Down 700 Down is the finest insulator Mountain Equipment uses. Its warmth-to-weight ratio, compressibility, long lifespan and softness are yet to be matched by man-made insulations. For all but the most serious expeditions, duck down is a great choice for both insulated clothing and equipment.
	Drilite Loft Drilite Loft is an exclusive range of highly water-repellent fabrics used in Mountain Equipment's insulated clothing and equipment. With a water-repellent coating that offers genuine water resistance (1,500 mm hydrostatic head), Drilite Loft fabrics remain highly water resistant throughout the lifetime of the product.
