The SOL Thermal Bivvy is a 4-season, durable and waterproof emergency sleeping bag that offers 80% body heat reflection.
Warm and durable in any season, the SOL Thermal Bivvy has a metalised, non-woven fabric that provides waterproof protection from the elements, whilst 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.
