Seems like a recurring issue. I had a very hard time getting the '85 lettering hoodie that the Baseball team had a few years back. I even talked to John and Lemonis about it. They didn't know how to get one. Good thing, I think, campus bookmart made some and I got one.
Good luck. I’ve been searching for that black STATE sweatshirt for 2 years.
Campus Bookmart does a good job of buying Badger clothing and printing merchandise that Adidas does make available to the public.
I bought a baseball hoodie from them that Adidas did not sell to the general public.
It’s not authentic but it works, I guess. I wish I could find the real thing.
