M-R Width: 72cm Length: 77cm This is the LEVEL 7 of the US military's ECWCS layering system. It's a well-known masterpiece. PrimaLoft, a synthetic down alternative, is used for the insulation, offering the advantage of retaining warmth even when wet. It's also said to be eight times warmer than down, and it's machine washable, so having one is essential for surviving a Japanese winter. This is an old, used item. Please refrain from purchasing if you are looking for a perfect item or are particularly concerned about the condition.
