The SOL Escape Bivvy is nothing less than a revolution in backcountry shelters. The complaint with most ultralight emergency shelters is the same; condensation builds up inside as you get warm, leaving your clothes soaking wet. With the Escape Bivvy, condensation is no longer an issue and you never again have to choose between staying dry and staying warm. The proprietary fabric lets moisture escape and at the same time keeps rain, wind and snow on the outside - all while reflecting your body heat back to you. Waterproof seams plus a drawstring hood closure and side zip mean you can seal out the elements entirely or use the bivvy like a traditional sleeping bag. The high visibility orange makes it easy for rescuers to see you even in areas with high tree cover.
