Made out of the same element-resistant, heat-returning foil as our Emergency Blankets for maximum portability and incredibly efficient body-warming, our Emergency Sleeping Pouches provide maximum coverage for the individual, insuring that body heat does not escape and insulating the user from moisture and wind. Providing the same heat reflection as our blankets but with superior coverage, nothing is as effective as our Emergency Sleeping Pouches at keeping you warm and safe from the elements in a disaster.
