The HELIUM BIVY from Outdoor Research is a must-have model in the Outdoor Research range. It's a highly effective bivy bag, heralded as the lightest, best-selling and most award-winning of all time.

Incredibly quick to assemble and disassemble, this ultra-light protective bag is 14% lighter than the previous generation and has everything the outdoor minimalist needs to be comfortable. It also benefits from durable, lightweight and waterproof Pertex Diamond Fuse technology, while its clamshell opening makes it easy to get in and out, and resists wear and tear for seasons of adventure to come.

This is the ideal shelter for minimalists looking to trade weight for speed, agility and performance.
