This is the Helium Emergency Bivy from OUTDOOR RESEARCH. This item is a new/unused product that has been stored indoors after purchase. The following is a description of the product: The Helium Emergency Bivy is an ultra-lightweight bivy that packs down smaller than a can of beer. When combined with a 3-season sleeping bag, it provides extra warmth, effectively turning it into a 4-season setup. Designed to trap warmth and protect your sleeping bag from rain and wind, it functions similarly to wearing a hard shell over a puffy jacket. It utilizes the waterproof and breathable Pertex Shield 2.5L material, known for its reliability in the Helium series, providing peace of mind with its waterproof performance. The simple design features an envelope shape and a drawcord closure, making it a palm-sized, ultra-lightweight bivy sack.
