Thank you for viewing. I purchased this at a store for about 20,000 yen. I couldn't find the tag, so I'm not entirely sure about the material, but I believe it's wool and polyester. It's a size M, but it's a slim fit. Also, there is some yellowing on the inner lining. - Brand: UNION STATION (Men's Bigi) - Color: Black - Style: Coverall - Size: M Please purchase only if you understand that this is a used item. Thank you.
