Good condition cold weather pants liner that could well be used by about any branch although I think they came from a naval aviator. But they might have been used by Army troops in Alaska, I don't know who exactly would or would not use this exact garment. There is a small strip of the lining cut out intentionally; it would match up with a lower pocket on fatigue pants and maybe someone stuffed the outer pocket inside to keep something in it from freezing. Made to wear with the insulation out, the green fabric in. That fabric feels silky but I think it is artificial and the fleecy insulation as well, however the insulation portion in feel and construction is more rug-like. Size is indicated as a Medium-Regular, you could likely wear over a further set of long johns as the waist measures 36" and the inseam is about 30" or a little over. In Good condition and probably worn a good bit but having a lot of life left in them and will likely outlast the career years anybody spends anyplace very cold and needs such a liner. USA only. If a flat rate box comes out cheaper than shipping by weight we will do so and adjust.
