GLACIER RANGE FEATURES

FILL

Down is a unique and exceptional insulation. It is more compressible, longer-lasting, and offers better warmth for its weight than any other fibrous insulation, achieving this through a structure that traps maximum still air while weighing as little as possible. Geese, Ducks and Swans all possess down feathers underneath their flight feathers, but as all of Mountain Equipment’s down is a by-product of the meat industry, our down is only sourced from Geese and Ducks. The down is removed from the birds at slaughter and processed to make it clean, hygienic and fluffy.

DOWN 700+

Our premium Duck down sourced from either within Europe or from China. With a cluster content of at least 90% and tested in individual batches to ensure a minimum fill power of 700. Some of the finest duck down available in the world and all DOWN CODEX® approved.

DOWN CODEX® APPROVED

In 2009 Mountain Equipment became one of the first outdoor brands to introduce independent auditing of our down supply chain. Quietly introduced, without fanfare or press-releases, DOWN CODEX® set out to understand an industry and supply-chain that was largely ignored and certainly little understood.

TRACE YOUR DOWN

All products contain a code that can be entered into our DOWN CODEX® website to trace the down that they contain. Not only can you identify the source of your down but the audit relating to that source and the down batch test results can also be viewed.

FIT

The fit of a sleeping bag is crucial in optimising performance.
A well-fitting sleeping bag is not only highly comfortable it also reduces dead air space and maximises thermal efficiency.

The fit across the Glacier Sleeping Bag range varies depending on the warmth of the bag.

EXPEDITION FIT

Glacier Expedition

With a more generous fit that is both longer and wider, these bags not only afford greater comfort when used for long periods of time but also enable additional clothing to be worn or stored within the bag easily.

MOUNTAIN FIT

Glacier 1000, Glacier 1000 Women’s, Glacier 700, Glacier 700 Women’s

The foundation of all our fit blocks, this semi-tapered mummy profile combines excellent thermal efficiency and comfort for all-round mountain use.

ALPINE FIT

Glacier 450, Glacier 450 Women’s, Glacier 300, Glacier 300 Women’s

Slightly more tapered in the upper body and in the legs than our Mountain Fit this fit maximises thermal performance and minimises weight.

EXL®*

Our time-tested EXL® system, a patented technology developed to provide extra warmth and extra loft, adds no weight but minimises dead airspace around the body, reduces drafts, and pulls fabric away from the down allowing it to loft maximally.

*In our Glacier Expedition and Women’s specific models only

FABRIC

Fabric technology is advancing all the time and we continually seek out those fabrics that offer the lowest weight, maximum breathability, compressibility and comfort.

DRILITE® LOFT™ 30

Considerably lighter than the original DRILITE® LOFT™ fabric, but still with the same highly water resistant 1500 mm hydrostatic head, DRILITE® LOFT™ weighs approximately 55g/m2 and is the ideal fabric for sleeping bags destined for serious mountaineering, climbing, and backpacking in difficult conditions.

Supersoft™ 30

Supersoft™ 30 is our legendary performer chosen for its breathability and durability. Weighing just 49g/m² provides exceptional durability with a soft hand and good breathability.

BAFFLES

Baffle structure is crucial to the performance of down sleeping bags. Without it, even the best quality down will not loft and insulate to its full potential. Baffles affect a sleeping bag’s durability, weight, and the migration of down inside them – they are the building blocks from which sleeping bags are made.

SLANTED BOX WALL BAFFLE

A slanted box wall baffle takes the classic box wall and offsets it to reduce thermal bridges and increase thermal efficiency. It also offers improved down migration control. An excellent lightweight construction technique that many other manufacturers would use in only their most premium bags.

TRAPEZOID 15:11 BAFFLE CONSTRUCTION

Trapezoid 15:11 baffles are used in the topside of the Glacier bags. A lighter and more efficient trapezoid profile, the 15:11 balances a greater need for weight reduction and compressibility alongside thermal efficiency. With less steeply angled side walls, this profile uses less internal stripping to remove bulk and weight. Ideal for weight-saving mountaineers who still want a very thermally-efficient construction method.

ZIP BAFFLES AND COLLARS

Our neck baffles and entry-zip baffles are vital in reducing the ‘chimney effect’ of hot air flowing out of the sleeping bag’s openings, and are also useful in reducing the ‘bellows effect’ of the movement of a restless sleeper pumping warm air from the bag.

LODE LOCK™ COLLAR CLOSURE*

Our Lode Lock™ collar closure with its low profile auto-locating closure combines all the advantages of a magnetic fastener with those of a mechanical lock. Rendering the traditional press-stud collar closure practically obsolete, its one handed quick release closure uses two captivated internal magnets to draw the locking mechanism together and ensure that once connected it cannot be accidentally opened. The result is an insulated collar that is more efficient and easier to operate. The collar’s down density is optimised so it moves with the user and contours to the body, while captive and elasticated drawcords ensure easy adjustment.

GEMINI™ ZIP BAFFLE*

Our Gemini™ baffle is found throughout almost our entire line of sleeping bags. It is a unique zip baffle system which replaces the bulky, down hungry twin draft tubes used traditionally on cold weather bags. The Gemini™ system is light, efficient, low bulk and supremely protective. It is grown on to the sidewalls of the sleeping bag: the integrated zip baffle utilises a continuous V-baffle system paired with a shaped and stiffened underside. With a greater contact area than a traditional tubular set-up, heat loss by convection is significantly reduced and radiative heat loss minimised. Tested through every step of its development, it eliminates heat loss almost entirely and at a fraction of the weight and bulk of more traditional methods.

HOOD

The head loses a lot of heat and is very sensitive to changes in temperature, making good hood design crucial to the performance of any sleeping bag. A good hood will also keep the neck warm and reduce the ‘chimney effect’ of hot air escaping the body of the sleeping bag.

DC5 HOOD

A 5 baffle hood that provides high levels of down control, low weight and excellent insulation. Its roominess imparts excellent versatility and, combined with the easy-run dual tether draw cords, superb comfort.

FOOT PIECE

Cold feet can spell the end of a comfortable night’s sleep or even the end of an expedition and we have unrivalled experience in designing innovative sleeping bag foot pieces. By controlling the down in a sleeping bag, the foot is kept warmer, and ensuring the foot piece fits perfectly around the lower body is crucial.

TRAPEZIUM 6

A six baffle foot piece, our most advanced design, and featuring both our Bulls Eye™ Technology and offset Sharks Toe™ foot construction. Its highly sophisticated baffle system maximises thermal efficiency for the coldest and most demanding environments, ensuring warm feet night after night.
