Low in weight and warm enough for early Spring and late Autumn use at higher altitudes or Northern latitudes.
Weighing 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.
The high-quality duck down has an actual minimum down cluster content of 90 % and is Down Codex approved.
