Floyd Mayweather Gennady Golovkin Andre Ward Canelo Alvarez Bernard Hopkins Jessie Vargas Klitschkos Haye Chudinov and Sturm Frampton Ricky Burns Jesse Hart Crolla Tony Bellew David Lemieux Dillian Whyte Roy Jones Etc etc. There are tons more but it'd take forever to list. More and more people switching to Grants, as they provide great protection and a hell of a punch. Will Cleto Reyes (Horsehair) Gloves be obsolete soon?
I see a lot of fighters switching/using Rival aswell. Everything ends up being about price & which company is wiling to pay the endorsment. (I'd assume a custom made glove is worth it for "Grant" to been seen on the hands if a high caliber fighter.
