Adidas 1/4 zip black polyester shirt

This is a nice Adidas 1/4 zip shirt. It is marked a size large but you can see how it fits on my size small manni, so I am guessing it's a youth large? But it fits me great as a size small so I'm listing it as a small just so the right size people see it. Measures approximately 21 armpit to armpit and 22 length in front, 24 in back. Great shape.
