The opinion of Aventure Nordique

The Helium Bivy from Outdoor Research is a bivouac bag with a lightweight, waterproof fabric made from Pertex Shield Diamond Fuse. This membrane protects you from moisture, rain and is breathable.

The advantage of the Helium Bivy is that it can be put up quickly and is very protective. It is an interesting alternative to a tent or tarp. It is quick and easy to assemble (1 hooded hoop), and then you can simply slip your sleeping bag inside.

Durable and protective :

  • 40 denier TPU laminated nylon on the ground level that rises high (bowl shaped), 30 denier Pertex Shield Diamond Fuse 2.5L nylon top.

  • Protective hood + removable mosquito net at the opening.

A small Delrin hoop keeps the hood at a height of about 50 cm above your head. 3 attachment points: 2 ground attachment points + 1 guy rope attachment point.

Depending on the weather, you can use two openings:

  • waterproof door: to be totally protected,

  • mosquito net door: to sleep with your head "under the stars" and to optimise air circulation.
