U.S. AIR FORCE physical training uniform, a navy nylon jacket. - Brand: U.S. AIR FORCE - Color: Navy - Material: Nylon - Size: M-R - Features: Physical training uniform Purchased from Military Wiper, but I'm selling it because I haven't had a chance to wear it. A rare and popular size!! Purchased USED about a year ago, only tried it on. There is some minor soiling, but it's in relatively clean condition. There are no cracks in the reflector part on the shoulders ✨ Thank you for looking.
