A benchmark in down sleeping bag design. Low in weight, compressible and easy to pack, these bags offer superb all-round performance in a more generously sized design.

Made with recycled materials and with features that would put many more expensive rivals to shame, the Classic Eco range of bags are ideal for all forms of self-supported travel, whether backpacking in Europe or trekking through the Himalaya.

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. All of Mountain Equipment’s down is a by-product of the meat industry, sourced from geese and ducks. The down is removed from the birds at slaughter and processed to make it clean, hygienic and fluffy.

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.

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

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.

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.

Perfectly adapted, the Mountain Equipment range of synthetic and down filled sleeping bags are the choice of today’s leading alpinists and arctic explorers. Ensuring comfort, protection and reliable warmth in the most extreme of environments. 100% of our down is Down Codex® approved and comes from independently audited and traceable sources.
