Outdoor Research Helium Bivy

Our Helium Bivy is a highly acclaimed bivy sack, lauded by our customers and outdoor enthusiasts. This ultralight bivy is incredibly easy to set up and take down, making it perfect for minimalists who value speed and efficiency. In addition, we have made the latest generation of the Helium Bivy even lighter, weighing 14% less than its predecessor. The minimalist design provides all the necessary features for outdoor adventurers to stay comfortable, while the durable, waterproof Pertex® Diamond Fuse technology ensures your gear stays protected. 

Thru-hikers and backpackers love the refined footprint and reduced weight of the Helium Bivy. The clamshell opening allows for easy access, resists wear and tear, and ensures that this bivy lasts for many seasons. It is waterproof, breathable, and fully seam-taped, providing the necessary protection from the elements. The no-see-um mesh prevents bugs from bothering you, while the single-pole system, two stake loops, one guy line loop, high volume toe end, and two internal fly fasteners make the bivy easy to pitch and secure.

To ensure visibility in low-light conditions, the reflective logo and trims add an extra layer of safety. Our Helium Bivy is the ideal shelter for those who prioritize agility and performance while minimizing weight.
