Full-Featured Bivy Sack

Able to withstand rain and snow, the Alpine Bivy by Outdoor Research is made of waterproof Gore-Tex Respiration Positive fabric that protects from the elements and keeps condensation out. The overlapped zipper opening lets you breathe freely without letting in a draft. At 32 ounces, it has a single pole that you can use to create overhead space or leave behind to lighten your load. Straps keep your sleeping pad in place and the removable netting keeps bugs out, while the hydroseal floor has an anti-fungal coating.
