Outdoor Research Helium UL Bivy

The Helium UL Bivy from Outdoor Research is an extremely lightweight bivy sack for solo adventurers traveling with minimalist gear. The high-quality 2.5-layer Pertex Shield material provides reliable protection against rain and wind, while the fully taped seams ensure additional waterproofing.

Unlike traditional bivy sacks, the integrated pole structure in the head area offers more comfort and distance from the face. The spacious toe box provides extra room for the feet. Ventilation flaps ensure pleasant air circulation and also reduce condensation inside.

The Helium UL Bivy from Outdoor Research combines the advantages of a compact bivy sack with the comfort of a minimalist tent, making it suitable for climbers, trekking trips, or as an ultralight emergency shelter for demanding outdoor adventures.
