Alpine Bivy

Outdoor Research equipped the two-pound Alpine Bivy with waterproof breathable Gore-Tex Respiration Positive to keep you comfortably dry while backpacking in wet weather. Gore-Tex's Respiration Positive provides more breathability than standard Gore-Tex membranes, giving you more comfort throughout the night. Outdoor Research's Hydroseal Floor and fully taped seams further prevent snow and rain from seeping through.

When it stops snowing and raining, the Alpine Bivy unzips to reveal a no-see-um mesh window for ventilated airflow and bug protection. There are straps inside to secure your sleeping pad, and an internal mesh pocket stows your alarm clock, smartphone, or GPS watch. Outdoor Research included five stake loops, a loop for a guy line, and a Delrin pole that you can either use for more headspace or leave at home to save weight.
