This is a brand new, unused men's M-sized LOGOSDAYS vest with tags. It's made of fleece fabric, which feels very comfortable and warm. I bought it at Shimamura a while ago and have kept it stored at home without using it. The tag says "navy," but the pajamas set I bought with it were navy, so the vest is actually black. It's recommended for cold days at home, as it won't get in the way.
