This is a long-sleeved T-shirt from Workman made with contact-cooling material. It's a men's S size in orange heather. The design is simple with a plain front and back. The fabric is thin with an uneven lining, so you can wear it comfortably even if you sweat. Although it's a size S, I think it can be worn by people up to around 170cm tall, unless they have a very muscular build. It's a new item with tags, but it has been stored at home, so please only purchase if you understand this. It will be folded small for packaging.
