The spacious Advanced Bivy™ can be used in place of a single-person tent. The largest of our bivy sacks, the Advanced Bivy™ provides space for thicker sleeping pads and loftier bags. The waterproof GORE-TEX® Respiration Positive™ fabric is incredibly breathable and blocks rain and snow, and the patented, removable dual-pole system increases ventilation and interior space. A zippered vent at the base improves airflow on humid nights.
