Earthrise Sleeping Bags

Recycled Down. Recycled Fabrics.

Recycled down, recycled fabrics; the Earthrise is our most sustainable range of sleeping bags which will give you years of excellent service. Based on the design of our best-selling Helium models, Earthrise sleeping bags are high performance products that boast both serious warmth and outstanding green credentials.

Down Cycle™ | Recycled Down

Following on from the introduction of our own Down Codex® project, Mountain Equipment is now introducing Down Cycle™. Starting with the introduction of clothing and sleeping bags made from 100% recycled down our ultimate aim is to introduce a fully closed loop recycling system for down clothing and equipment and to eliminate the need for unwanted products or those at the end of their useable life being sent to landfill.

Earthrise Range Features

Fill

Our recycled down has exceptional environmental credentials while maintaining superb performance. Sourced from a European facility powered by solar power which sorts and separates post-consumer down and feather products that were otherwise destined for landfill. The down and feather is washed in a plant with extremely efficient water recycling, and then it is graded for quality. We buy only the finest grade of recycled down, in excess of 650 fill power, guaranteeing not only an ethical purchase but a high performance one.

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.

Alpine Fit

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 women’s specific models only.

Fabric

Earthrise 20D

With the fantastic drape, softness and lustre usually associated only with fabrics made from virgin materials, our Earthrise fabrics are environmentally-sound fabrics with a performance heritage. 20D yarns combine to make a very wind resistant, comfortable, and downproof fabric which has sustainability chops that are hard to beat. And, at 45 g/m2 it won’t weigh you down.

Recycled Lining

Sustainability and performance combine in a soft, breathable and durable lining fabric that is 100 % recycled and weighs just 59 g/m2. Environmental benefits without sacrificing function or aesthetic.

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.

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 4

A four baffle foot piece featuring our unique Bulls Eye™ Technology and offset Sharks Toe™ foot that is engineered for our lightest technical sleeping bags. Its baffle construction restricts down migration whilst keeping weight and bulk to a minimum.

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.
