All about this product



The Helium Bivy is one of the lightest awarded bivy sack. Incredibly quick to set up and breakdown, the ultralight Helium Bivy is 14% lighter than its last generation, and has everything the outdoor minimalist needs to be comfortable. Thru-hikers and bike-packers love the Helium for its refined footprint and reduced weight, and trust it for its waterproof and breathable Pertex Shield+ fabric that doesn't compromise on durability. A no-nonsense clamshell opening is sure to handle seasons of adventuring to come. This is the ideal shelter for minimalists who are looking to trade weight for speed, agility, and performance.
