Adidas Men's 3-Stripe Tennis Polo T Shirt

Nice tennis shirt never worn or laundered but I did remove the tags, it is light and breathable very soft comfortable material and dropped back hem with those triangles on the hem on each side which I have no idea what they are called but I like in my shirts. I had an idea that I was going to class up my act and start wearing a collared shirt as I was playing a lot of tennis at a fancy/schmanzy club down south. I bought this bored waiting for a connection coming back north in Houston airport just as Covid hit. So now I have gained twenty pounds or so and now it is too small. More accurately I am too large.
