SMU Mustangs Football Retro Angry Mustang CrewneckSMU football has been as tough as the mustangs who've represented the school throughout the years, including this fuming cartoon stallion from the late 1960s. He encapsulates the energy of SMU's live mascot, Peruna, named for a Prohibition era "medicine" with a similar kick as the miniature stallion. Products are mocked up on a size S. Graphics may appear smaller on larger sizes.
