This is a Workman long-sleeved raglan T-shirt with heat retention properties. It is a light gray men's size M. I believe this item was released this year. It is made of a stretchy material with a waffle-like texture on the outer fabric. There are no prints on either the front or back, and it has a simple design. This item is new with tags, but it has been stored at home, so please only purchase if you understand this.
