The Escape Light Bivvy is nothing short of a revolution in the field of ultra-light emergency shelters. Designed by the brand Sol, this nan offers an exclusive fabric that allows moisture to escape while keeping rain, snow, and wind out – all while reflecting your body heat. The waterproof seams, along with the drawstring closure and side zipper, allow you to fully seal the bag or use the Escape Light Bivvy as a traditional sleeping bag.
