4/$25 MSU Spartan windbreaker

Campus Den Michigan State University gray pull over quarter zip wind breaker with the MSU green and white spartan head. Size small (I believe this is unisex) Zips up to neck. Two zip close pockets, one on each side. One zipper on bottom side to get on and off easily. Only flaw is a minor stain/mark on the front, bottom, middle area. It’s hard to tell, but easier to see in some lightening once you notice it. You can see it better in the last photo. Unsure of what it is and if it can be treated or not to get out.
