Perfect for backpacking and trekking in cold but dry conditions. Whether staying in unheated tea-houses in the Himalaya or winter rooms in the Alps this warm but lightweight bag is ideal.
Helium fabrics are exceptionally light, compressible and tough. There densely woven construction ensures the highest levels of down-proofing, wind resistance and resistance to heat loss.
Mountain Equipment's high-quality duck down has an actual minimum down cluster content of 90% and is DOWN CODEX approved.
By utilizing slanted box-wall baffles throughout the entire main body of our Helium bags meaningful weight is removed from the bag’s structure. On the very lightest models, further weight savings are gained by the use of stitch-through baffles. The use of mid-level side-seams affords great versatility whether the bag is laid on its front or back and this is also reflected in the distribution of fill which, whilst slightly favouring the top side allows plenty of fill to remain in the underside, foot piece and hood.
