Versatile down sleeping bag with comfortable fit

Mountain Equipment’s Helium 400 compression stuff sack is made from waterproof material and provides secure protection against bad weather when travelling or hiking. The mummy sleeping bag is constructed with the cosy Alpine Fit 2.0 and offers plenty of space. The down sleeping bag can be transported in the compression stuff sack to comfortably fit in your trekking backpack.

Warm, cruelty-free down

The fill consists of pure duck down with a fill power of 700+ cuin. It is certified according to the cruelty-free Down Codex Standard that also focusses on a sustainable production. The breathable Helium outer and the Supersoft inner are made from recycled fibres. A PFC-free DWR finish keeps the Mountain Equipment Women's Helium 400 down sleeping bag from absorbing moisture.
