Low in weight and warm enough for early Spring and late Autumn use at higher altitudes or Northern latitudes.
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.
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 downproofing, wind resistance and resistance to heat loss. The new HELIUM 20 offers greater handfeel over previous HELIUM fabrics as well as reduced seam slippage, resulting in even greater durability than the previous fabric.
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.
