Thermo-Lite 2.0 Bivvy Sack

The 6.5oz Adventure Medical Thermo-Lite 2 Bivvy provides an emergency shelter for day trips that run a little long, and it can even replace your sleeping bag in warm weather. This water-resistant bivy sack gives you insulation similar to a 50F sleeping bag, so you can bring it alone on ultralight overnight trips in the summer. The Thermo-Lite 2 nylon material holds in heat and fights off moist weather during an un-planned overnight stay in the backcountry.
