Nike Pro Aeroadapt Men's Training T-shirt - Small

For sale is a used Nike Pro Aeroadapt training/athletic short-sleeve t-shirt top in gray, men's small. I bought this shirt new and it was once my favorite shirt for running. The shirt has oil stains on the chest from where I had to use Vaseline while running the 2021 Chicago Marathon. The shirt also shows abrasions on the torso, sides, and back from a running vest. The shirt is made of a smooth, stretchy material with a vented panel on the shoulders and back that is intended to raise when you sweat to release heat. There are black accents on the shoulders and back of the neck, a black swoosh in the middle of the chest, and Nike Pro lettering on the left side. The shirt is 91% polyester and 9% spandex. The fit is slightly looser around the shoulders and arms than other Nike shirts I own.
