The Helium 250 XL is a longer and slightly wider bag for users up to 6ft 5 inches. It's the perfect bag for summer backpacking, alpinism and cycle touring. It weighs very little (a little over 700g) and it packs tiny too.
Weighing just 38g/m2, HELIUM™ 20 outer fabric 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.
High-quality duck down has an actual minimum down cluster content of 90% and is Mountain Equipment DOWN CODEX approved, this means you can plug your products unique code into their website to track the source of the down in your bag.
A Trapezium 4 baffle foot piece featuring ME's unique Bulls Eye™ Technology and offset Sharks Toe™ foot that is engineered for their lightest technical sleeping bags. Its baffle construction restricts down migration whilst keeping weight and bulk to a minimum.
Finally, body heat retension is optomised by utilizing slanted box-wall baffles throughout the entire main body of the bag so that 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.
When it comes to sleeping bags; Mountain Equipment really know their stuff!
