Bivy was custom made for me several years ago by my wife, who is a professional seamstress. The fabric on the topside is called Milair, which is a waterproof/breathable fabric you don’t hear about anymore. It’s basically a PU coating. The bottomside is silnylon.

The bivy is long enough to fit a size Long sleeping bag, and wide/deep enough to fit a big zero degree bag if desired. It has a pullover hood, but no zipper or poles.

Weight is 11.15 ounces.
