Breakdown
The Helium Bivy is Outdoor Research's lightest, best-selling, and most awarded bivy sack of all time. Incredibly quick to set up and break down, the ultralight Helium Bivy is 14% lighter than the previous version and has everything the outdoor minimalist needs to be comfortable. Backcountry hunters love the Helium for its refined footprint, reduced weight, and durable waterproof Pertex Diamond Fuse technology. Bivy's give you the ability to trail game from day to day without having to go back to a base camp. The clamshell opening makes it easy to get in or out, and resists wear and tear for future adventures to come. This is the ideal shelter for minimalists who are looking to trade weight for speed, agility, and performance. The bivy sack alone can be added to any sleep system to add water protection from condensation from the walls of your tent.
