In a world of challengers, each of the Glacier models sits first among equals. Developed specifically to be best in class they offer true all-round performance and protection for unreliable conditions. Whether you are on a 3-week tent-based trek in the Himalaya, hauling a pulk across the Greenland icecap or mountaineering in the Cascades there is a Glacier bag for almost every mountain and cold weather adventure.

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.

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.

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.

Baffles, Zip Baffles and Collars

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.

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.

Hood and Foot Piece

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.

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.
