Weighing in at just 18 ounces, the Outdoor Research Helium Bivy is built for the stingiest of ounce-counting adventurers or anyone looking for an ultra-lightweight backup shelter. High-performance Pertex Shield+ balances weight, durability, waterproofness, and breathability.
Measuring 84” x 26” at the head and tapering to 20”wide at the feet, the bivy is large enough to accommodate most sleeping bags and standard-sized sleeping pads. An integrated shock-corded Delrin pole runs over the top of the bag, keeping material off of your face and providing 19.5” of headroom while you are lying flat on your back. To shed weight, you can remove the pole entirely. Extra volume is built into the foot section of the bivy to provide a little wiggle room and increase livability.
Despite its light weight, the Helium Bivy still delivers durability and reliable protection. A 70D laminated floor is surprisingly rugged and full seam taping bolsters waterproof protection. Integrated No-See-Um mesh at the head of the bivy enhances breathability when weather cooperates while the bivy can be fully enclosed to fend off the elements.Other features include integrated sleeping pad straps, five stake loops (stakes not included), and an internal mesh pocket for stashing valuables.
