The Mountain Equipment Helium 400 Down Sleeping Bag is an incredibly light, versatile and packable sleeping bag well suited to backpacking and cycle touring that will still happily cope with cooler nights during the spring and summer months.
Helium: 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.
Down 700: Our high-quality duck down has an actual minimum down cluster content of 90% and is DOWN CODEX approved.
Optimised: 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.
Inner/Outer Fabrics Helium™ 20: Weighing just 38g/m2, HELIUM™ 20 uses 20 denier yarns to create a fabric that is compressible, tough, and extremely comfortable. Its densely woven construction ensures the highest levels of down proofing, wind resistance and resistance to heat loss. The new HELIUM™ 20 offers greater hand feel over previous HELIUM™ fabrics as well as reduced seam slippage, resulting in even greater durability than the previous fabric.
Supersoft™ 30: Supersoft™ 30 is our legendary performer chosen for its breathability and durability. Weighing just 49g/m² provides exceptional durability with a soft hand and good breathability.
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.
