This is a Gold's Gym T-shirt. The size is L. The color is dark gray? Gray blue? I looked it up but couldn't find it, so please judge from the photos. This is a used item, so please understand that there is some wear and tear. The lower back area on the back side is slightly fuzzy. (See photo 4) I am also listing other Gold's Gym T-shirts. If you purchase them together, I can offer a discount. Thank you.
