This is an AKM raglan hoodie. The hoodie is designed with a structural pattern to fit the body. It uses a fabric with a high ounce count, but it also contains some polyurethane, so it's stretchy and shouldn't restrict movement. The greatest appeal of this item is its structural and functional design. I bought it about two years ago, so some people may notice some wear and tear, but there are no noticeable stains or functional defects. The retail price was around 70,000 to 80,000 yen.
