Product Review

Made from the same fabric as our go-to ultra lightweight rain shell, the Helium II Jacket, the Helium Bivy is the most lightweight bivy we make, weighing in at a feathery 18oz. Featuring a classic, no-nonsense clamshell design, completely waterproof, breathable and ready for many seasons of adventuring--thanks to the 70D floor--the Helium Bivy is a true minimalist bivy for fast and light solo expeditions.
