      Classic Eco Sleeping Bags

      Via Graffer, Campanile Basso, Dolomites

    100% Recycled Down, 100% Recycled Fabrics

    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.

    Built Better

    Our Classic Eco range of sleeping bags offer excellent all-round performance and warmth.

    Now constructed with 100% recycled down and 100% recycled fabrics, these bags are among the lowest impact down bags we offer, and are a great option for those who wish to make a more sustainable choice, without compromising on performance.

    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. 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.

    Down Cycle is part of our commitment to do business in a more sustainable way. It began in 2017 with the introduction of 100% post-consumer recycled down into our Earthrise range of clothing but also includes a much more ambitious plan to create a functioning closed loop recycling system, ensuring down clothing and sleeping bags which are either unwanted or at the end of their life do not simply get thrown away.

    Features | 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.

    • Mountain Fit

      The bags in this range use a mountain fit which is a little more spacious than our alpine fit, while remaining thermally efficient. This can gives you a bit more space on longer trips, and at times when not every gram counts.

    Features | 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.

    • 100% recycled Earthrise shell

      All the fabrics in the Classic Eco Bags are 100% recycled and fluorocarbon free. The outer shell is lightweight, while remaining downproof and durable enough for extended trips.

    • Supersoft 20D

      The inside of the Classic Eco bags are all lined with 100% recycled Supersoft 20D lining fabric with PFC free DWR, chosen for its breathability and durability.

    Classic Eco 1000 Women's: -17°C/1°F

    Features | 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.

    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.

    • 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.

    • 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.

    Features | 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.

    • 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.

    • 2 baffle anatomically shaped and offset foot piece

      A 2 baffle foot piece baffle construction restricts down migration whilst keeping weight and bulk to a minimum.
