This is an Under Armour training cut-and-sew shirt. The size tag has faded, but I believe it was LG. It's a shirt that can be worn loosely. Width: Approximately 58cm Length: Approximately 70cm The fabric is probably polyester, and it also has mesh parts, making it highly moisture-wicking and quick-drying. The left side of the abdomen can be opened and closed with a zipper. A rubber string is attached to the right side of the abdomen. There is some black staining on the white line around the left shoulder. I think it can be worn all season. Please refrain from purchasing if you are sensitive to imperfections. No price reduction is possible. It will be folded and shipped.
