As seen on HBO’s “24/7” and Showtime’s “All-Access” series, the infamous Roger Mayweather Custom T-Shirt is now available online.

Spawned from creator Ludan Taquiqui, the shirt’s slogan “U DON’T KNOW SH*T ‘BOUT BOXING” is a catchphrase that Mayweather, a former two-division world champion and current day trainer, made famous.
