Cal Poly's men’s basketball won their first ever game in the NCAA, and now the campus’ spirit is ever-growing.

The school is even selling a special shirt which commemorates the Big West win.

They began selling them on Tuesday and, already, sizes and versions are sold out.

Students who bought the shirt say it will be a bit of history years from now; it'll remind them of Cal Poly's first Big West championship win and their first win in the NCAA yesterday.

The Mustangs are going on to play the undefeated Wichita State tomorrow, and many more are wanting a shirt in time to watch that game.

Though, fans do believe there will be plenty more shirts like this--they just want the first one.
