Cassius Clay, aka Muhammad Ali, one of the greatest boxers of all time, is being recognized by Roots of Fight this spring with a tribute shirt and sweatshirt. The tribute shirt is an example of plain elegance, sporting Ali’s name on the front and featuring a “Sweet Science” graphic on the back, complete with crossed flags and boxing gloves. The sweatshirt has a distinctly retro feeling, with a picture of Clay in his glory days, and U.S.A. 1960 printed at the top. The same “Sweet Science” graphic appears here as well. Give this boxing legend the recognition and memory that he deserves by sporting his signature vintage clothing at the next big MMA event, and remind yourself (and others) how far this sport has come.
