Light and totally unrestrictive, this lightweight quilt can also form a basic bag for summer tent and tarp camping.In their new guise, lighter and warmer for their weight than ever before, the Helium collection looks destined to be our bestselling yet again. Efficiently sized, supremely comfortable and low in weight each Helium bag offers outstanding all-round performance for backpackers, cycle-tourers and trekkers. These bags don’t skimp on features and will keep you warm and comfortable whether on a summer road-trip or extended trek.
By utilising 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. The overall fill distribution also allows down density to be optimised. Higher densities of fill are favoured in the underside of the bag, the underside of the hood, and the foot piece to maximise thermal efficiency and minimise migration, whereas the collar and zip baffle can make use of lower densities. This serves to improve comfort (as the collar in particular seeks to wrap around the user) and improve warmth, reflecting the lower levels of heat which are lost through the side of bag and allowing higher concentrations of the overall fill to remain within the main body of the bag.
