The size is not indicated, but it's approximately men's M to L. It's a reversible blouson. The outer fabric is a gray check pattern with thin lines (this was used as the main side). The lining is a solid gray cotton material, similar to a sweatshirt or hoodie. There are pockets on both the chest and waist when using the check pattern side, and pockets on both waists when using the gray side. It has the feel of a zip-up sweatshirt. When reversed, the pockets become inner pockets. The collar is a stand-up collar. The ribbed parts have a border pattern. The appearance changes quite a bit depending on which side is worn. For spring and autumn. For spring and autumn. I think the condition is not bad, but it's still used, so please consider carefully if you are sensitive to this.
