80's US Military Issue Anorak created as "snow camoflauge" to be worn over cold weather military coats in order to blend into snowy surroundings. The owner of this piece wore it in the 80's while being stationed in Alaska. It is a lightweight piece. Marked M - Fits like XL. I wear an XS and I wear this very oversized. Can fit a range of sizes from XS-XL depending on how you like it to fit.
