Thank you for viewing. This is an orange ALPHA LINER SYSTEM M-65 FIELD COAT, made of nylon, lightweight and excellent in heat retention. It's a US size L. It is not a government-issued item. This is an Alpha Industries liner. I used to wear it set in an Alpha Industries parka. The liner can be worn on its own, and of course, can also be attached to the US military M65 jacket, etc. Also, unlike the actual US military liners, this liner has jersey cuffs, which prevent cold air from entering, so it's very warm. As it's an "authentic" Alpha Industries product, the button positions for attaching the liner perfectly match Alpha Industries parkas, making it comfortable to wear. Also, the rescue color liner is rarely seen, so it's recommended. In case of rescue or search (for the person being rescued), having a rescue color on the inner layer is helpful. Of course, this is a fantasy. I bought this item considering such a scenario. Of course, I never became a person in need of rescue. ※It is not a licensed product manufactured by a Japanese manufacturer, but made in the USA. - Color: Orange - Size: LARGE (67 to 71 inches height, 41 to 45 inches chest) - Material: Outer: 100% Nylon, Filling: 100% Polyester - Model: ALPHA LINER SYSTEM M-65 FIELD COAT - Country of Manufacture: Made in USA No stains, tears, or odors.
