Outdoor Research Helium UL Bivy

When every gram matters and your campsite is wherever the day ends, the Outdoor Research Helium UL Bivy delivers dependable weather protection in an incredibly lightweight, packable design.

Built for fast-and-light backpacking, alpine climbing, bikepacking and minimalist wild camping, this updated bivy provides a comfortable refuge without the weight and bulk of a traditional tent.

Constructed with bluesign® approved Pertex® Shield NetPlus® fabric made from recycled nylon, the Helium UL Bivy offers fully waterproof, highly breathable protection with fully taped seams and a durable PU-coated floor to keep you dry when conditions deteriorate. A single DAC aluminium pole creates generous headroom, while the high-volume toe box provides extra space for greater comfort throughout the night.

The redesigned clamshell opening makes getting in and out easier than ever, and dual passive ventilation flaps help minimise condensation by increasing airflow without compromising weather protection. Reflective detailing improves visibility in low light, while the compact packed size makes it easy to stash in your rucksack for multi-day adventures or emergency shelter on big mountain days.

For those wanting additional covered storage or more sheltered living space, the Helium UL Vestibule is available as an additional purchase. It quickly attaches to the bivy to create a lightweight vestibule that's perfect for storing gear, cooking in poor weather, or simply enjoying a little extra room around camp.
