Not black and Runs small
Size: X-Large, Color: Black
I ordered black but it was more like charcoal gray. I ordered a XL and it fit like a Large at best. The fabric was very soft, so that was a positive. Very disappointed in the color and sizing. I reordered a 2XL and it also runs very small. It fit about the same as the XL did. It is a athletic fit. There is barely any size difference between an XL and a 2XL. Highly recommend to not waste your money on this shirt.
