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
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.
