Floyd Mayweather is TRIPLING DOWN on Gucci ... rocking the brand from neck-to-toe -- but he ain't about to hear comments on the matter -- dude disabled 'em from his social media!!!
Gucci has faced major criticism over the past month after the apparel giant released a sweater that many called "racist" because it appears to be blackface -- but Floyd's still riding with them.
Mayweather backed them on a massive shopping spree last week ... he backed them on his private jet just a day later ... and on Monday, he took it one step even FURTHER.
