Helium Bivy

The Helium Bivy is Outdoor Research’s super lightweight version of their classic Alpine Bivy. Made from tape-sealed Pertex Shield+ with a reinforced base and bug mesh closure, it features a single lightweight pole to keep your face unconstricted. Ingenious design additions include: straps to keep your sleeping mat in place, a mesh pocket near the head, peg loops and a guy line to keep the bag in place. There’s also plenty of space down the foot end to store a small pack. This is the Prince of Bivy Bags.
