this isnt MMA Gear... its a prop mask from any prop shop XD or you could go to mayhems myspace site and ask him there.......... ~Foz
isn't it a lucha libre mask? if so highspots.com has a good selection of them, not sure exactly which one Mayhem wears, but you could get one somewhat like it.

Well that's it. Man I had no intrest of getting one but only $29 and that thing actually looks pretty sweet. I just might sport something like that while warming up before a fight.
Yeah Highspots is the shit for finding hard to find wrestling music cd's. I use to be in the game they use to sponsor my site Thememasters.com
