USN/USMC type.  VietNam era issue.  Leather with an, I think it's fur, fur trim collar.
Zipper looks to be brass.  Cuffs are stretchy kinda knit fabric.  With a band of the same knit stretchy stuff around the bottom.
Lining is kinda like silk, or satin I think.
I used to hear reports of really bad work in these so i'm concerned.  Would rather leave it as it is then have it f--d up.
When I got out, no one to take it back, so I kept it.
