This is a Moncler blouson, a MA-1 type, featuring a combination of different materials. The body is made of wool, making it warm enough to be worn as an outer layer. The size is M. It's a bit oversized, so it's closer to a size L. The measurements are approximately 52cm wide, 68cm long, and 64cm sleeve length. This is an authentic item purchased at a Moncler directly-managed store in Japan for around 240,000 yen.
