T-shirt’s or sweatshirts or hats.
Ty!
Try Gameday.
Gameday on Green St. typically has a broader selection of major/college-specific swag than what is offered online. Better pricing in the store than online, oftentimes.
You can go to the Illini Union Bookstore site. They have an Illinois Engineering t-shirt available, and it’s relatively inexpensive. Just got one for our newly-admitted daughter!
