Condensation is no longer an issue with the AMK SOL Escape Bivvy.  You can stay warm AND dry. The spunbonded olefin fabric lets moisture escape at the same time that it keeps rain, snow, and wind on the outside.  The metalized coating reflects you body heat allowing you to stay warm.  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, and the low-visibility olive drab exterior makes it easy for you to blend in with your surroundings.
