Charles Lewis founded TapouT in 1997, prompting a whirlwind life that intersected the birth of a sport. Selling TapouT apparel out of the trunk of his car during road trips throughout California, a hot bed of mixed martial arts in the late 1990s, Lewis took on the superhero persona of “Mask" as he donned war paint on his face and wore outlandish comic book outfits.
