Dimensions: 32" x 82". 5.5oz. High-visibility orange exterior is easy to spot by rescue personnel. Features a proprietary spunbonded olefin fabric with a metalized coating designed to keep you warm and dry in any conditons. Breatheable - lets moisture escape at the same time that it keeps rain, snow and wind on the outside, 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. Can also be used as a liner in a traditional sleeping bag. Packaged in drawstring rucksack.
