Outdoor Research Helium Bivy - slate

Helium - Lightweight, bombproof weather protection for solo adventures

The Helium Bivy is the ultimate lightweight shelter for the solo adventurer, whether logging miles while fastpacking, bikepacking down the coast, or setting personal bests during long days on the wall.

Built with innovative Pertex® Shield Diamond Fuse 2.5L technology, the Helium Bivy is engineered for low-profile waterproof and windproof protection. The breathable, fully seam-taped construction ensures a dry and comfortable night's rest, while the no-see-um, bluesign® approved polyester mesh offers an unobstructed view of the night sky, even when the bugs are out. The clamshell opening paired with two internal fly fasteners make entry and exit a breeze, while the high volume toe end means more room and comfort for feet. And when the wind howls, the single-pole system, one guy line loop, and two stake loops stand firm. Reflective logos and trims enhance visibility as dusk falls on your backcountry retreat.

Designed to move light and fast when weight and performance matter the most, the Helium Bivy is a protective, breathable cocoon perfect for solo adventures.
