Be the first to review this product

The largest of our bivy sacks, the spacious Advanced Bivy provides the most space for thicker sleeping pads and loftier bags, and can be used in place of a single-person tent. The patented dual-pole system increases ventilation and interior space, or the second pole can be left behind when weight and pack space are critical. GORE-TEX® Respiration Positive™ fabric allows warm, moist air to escape but blocks outside weather, minimizing condensation while providing supreme protection from the elements. A zippered vent at the base improves airflow on humid nights.
