For warmth and durability in any season, the SOL® Thermal Bivvy has a metalized non-woven fabric that provides waterproof protection from the elements while reflecting 80% of your body's heat back to you. The SOL Thermal BIVVY offers more versatility than traditional emergency sleeping bags - the extremely durable fabric resists rips and tears, and thanks to its soft face and aggressive side-venting, it can be pushed into duty as a stand-alone sleep system in warmer weather. Ideal for outdoor users looking for an emergency shelter that can become a regular part of their gear arsenal.
