It's brushed like a 100% wool jacket, making it warm and light. Plus, thanks to the polyester, it's durable and wrinkle-resistant, making it easy to care for. It has a welt pocket on the chest and patch pockets on both sides. There is one patch pocket on the lower left side inside. The labeled size is L, and when measured flat, the length is 74cm, the shoulder width is 47cm, and the chest width is 52cm. There are no noticeable scratches or stains.
