This is a Workman long-sleeved crew neck thermal shirt. It's a men's size M. The upper part of the body is navy, and the lower part is black, with a color block design. It features block fleece lining. It has thumbholes in the sleeves. It was released last year, but it's only available in some stores this year, so it may have been discontinued. It's a new item with tags, but it has been stored at home, so please understand this before purchasing.
