Enthusing the Alpinist’s spirit, the Helium range of bags blend craft with function in an otherwise remarkably simple package. Now made from PFC-Free and 100% recycled fabrics the Helium range also benefits from a new more comfortable, yet technical Alpine 2.0 fit and revised collar in selected models. These bags continue to offer classleading levels of design and functionality and will keep you warm whether hiking a long distance trail or on a Himalayan trek. Low in weight and and pack size this is a bag that's warm enough for early Spring and late Autumn use at higher altitudes or Northern latitudes. Helium 20Weighing only 38 g/m², helium 20 uses 20-denier-yarns to create a fabric that is compressible, robust and extremely comfortable. Its densely woven construction ensures maximum down density, wind resistance and heat loss resistance. The new Helium 20 offers a better hand feel than previous helium fabrics and reduced seam slippage, resulting in even longer durability than the previous fabric. Down 700The high-quality duck down has an actual minimum down cluster content of 90 %, has a fillpower of 700 cuin and is Down Codex approved. Down CodexMountain Equipment's Down Codex controls and reduces the risks within a down supply chain in order to meet the high animal welfare standards and the high quality standards. The goal was also to present the complexity of a down supply chain in a comprehensible and above all transparent way.
