mayweather commissioned specially-designed mouthguards for the fight by dr. lee gause, owner of iceberg guards, costing $25,000. along with "subtle" clear pairs, some of them contained gold leaf, diamond dust and an embedded $100 bill. iceberg guards also released a limited-edition tmt-branded mouthguard to tie in with the fight. pacquiao's mouthguard was designed by dr. ed dela vega of canoga park, los angeles, who has custom-fit mouthguards for pacquiao and other philippine boxers. it featured a multi-colored design with a blend of the colors from the flag of the philippines, meant to represent the different ethnic groups that support him. unlike mayweather's, this mouthguard was supplied as a gift to pacquiao; vega argued that mayweather's high-cost mouthguard was simply "hype" meant to "rub it in the face of boxers who can't afford it".
