Description

Waterproof Protection Without the Weight

The Helium UL Bivy is built for ultralight backpackers, climbers, and fast-packers who need waterproof protection and breathability in a minimalist shelter.

Made with bluesign® approved Pertex® Shield NetPlus® fabric from 100% recycled nylon, the Helium UL Bivy is newly updated for 2026 to deliver durable, lightweight performance with a fully seam-taped design and waterproof PU-coated floor for reliable weather protection. Dual passive ventilation flaps improve airflow and reduce condensation, while a high-volume toe box adds comfort through the night. A clamshell opening, single DAC aluminum pole, and six stakes/stake loops make setup quick and efficient in any terrain.
