60 days to change your mindThe Helium Bivy is a bivy bag from Outdoor Research.
This model is the lightest and the most sold from Outdoor Research.
14% lighter than its predecessor, it is extremely quick to set up and take down to make your fast-paced bivouac experience as comfortable and space-saving as possible.
Its fabric is particularly appreciated for its lightness, durability and waterproofing thanks to Pertex® Diamond Fusetechnology. Its flap opening makes getting in and out easy while also making it very resistant, making the Helium Bivy a long-term investment!
The Helium Bivy has a tapered shape, which will work best with tapered mattresses for a better fit, ideally 48 cm at the feet or less.
The Helium Bivy is a lightweight, high-performance and durable bivouac bag for explorers looking for a minimalist approach!
