authentic army field jacket, about 20 years old, i do not use it, simply hangs in closet. button in or out liner, connected hood in zippered back collar. warm, however heavy. a pal of mine got it for me from the PX at Ripley. size says medium, around a 42" chest. plenty long enough. i used it, was 5-10 and 160. hardly any use. mile north of brainerd.
