The spacious Advanced Bivy™ can be used in place of a single-person tent. The largest of our bivy sacks, the Advanced Bivy™ provides the most space for thicker sleeping pads and loftier bags. The patented dual-pole system can be used to increase ventilation and interior space, or 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.
