Outdoor Research Helium Bivy in Coyote for lightweight shelter and bug protection
A lightweight, seam-sealed bivy with waterproof, windproof and insect-resistant protection for solo nights outdoors.
The Helium Bivy is a compact bivouac sack from Outdoor Research, made for nights when you want a low-profile shelter with weather and insect protection. The Coyote colour keeps the look understated, while the build focuses on being lightweight, durable and easy to carry.
It uses a 1 pole system and secures with 4 stake loops plus 1 guy line loop. The clamshell opening has 2 internal fly fasteners, and the toe end offers extra volume for storing essentials.
Materials and protection
The bivy is made from 100% nylon, with a 30D ripstop upper and a 40D TPU laminated floor. The fabric is described as highly abrasion resistant, waterproof and windproof, while still remaining breathable. A No-See-Um Mesh helps with insect deterrence, and the seam-sealed construction adds another layer of weather protection.
Points to keep in mind
- It is a single-size bivy intended to fit an adult user.
- The low-profile format suits minimalist overnight setups rather than roomier tent-style camping.
- The emphasis is on lightweight protection, not on extra living space.
For hikers and campers who value a small packed size and straightforward shelter, the Helium Bivy keeps the setup simple without losing the core protection a bivy bag is meant to provide.
