Outdoor ResearchOutdoor Research Helium Ul Bivy Spice

Helium Ul Bivy from Outdoor Research is an ultralight bivy sack developed for you if you want protected sleep with minimal pack weight during hiking, climbing, or fastpacking. You get waterproof weather protection that also releases moisture from the inside, so you can sleep securely even when the weather changes.

The bivy combines a lightweight outer fabric with fully taped seams and a waterproof floor that keeps out moisture from the ground. The simple pole construction with a DAC aluminum pole provides a little extra space over the upper body, while the toe box is raised for more comfort around the feet. A clamshell opening makes it easy to get in and out, and mesh panels with passive ventilation help release moisture and reduce condensation while you sleep.
