Vintage military N-3B jacket. The SCOVILL zipper suggests it's from the 1970s. There are stains on the back, and some dirt and tears on the inside. While there are some stains that won't come out, it has been cleaned and is sanitary. I'm 174cm tall and weigh 70kg, and it fits me perfectly, so it's equivalent to a Japanese size M to L jacket. Photos 18 and 19 show me wearing it. This is a vintage item from a specific era, so please purchase only if you understand vintage clothing.
