This is a Camp 7 down vest. I purchased it at a vintage clothing store in the US, so it shows signs of wear. There's a mark on the neck tag that looks like the original owner's name (photo 7). There are also stains as seen in photos 3, 4, and 5, as well as small, hard-to-see stains. Made in USA Length: Approximately 68cm Width: Approximately 48cm Size: S Since it's an American size S, it's about a Japanese M. Please understand that this is a vintage item before purchasing.
