There are no overall stains or spots, but please refrain from purchasing if you are sensitive to such things. BUZZ RICKSON Mods Coat Fishtail Parka The M-51 parka evolved from the M-48 parka, a pullover type that developed from World War II, and was mainly issued to US Army officers and soldiers in the cold regions of the Korean War. This battlefield was a cold region that the US military had never experienced before, so a layering system was adopted to be worn over regular equipment. The shell of the initial model (1951) was made of thick cotton satin, but in models after 1952, the material was changed to cotton-nylon oxford cloth to reduce costs and weight. The cuffs have rubber strap adjuster belts built in to increase the seal, and the pocket bags are made of warm wool material. Color: Olive
