Hi Gambit! Nice to see you here.
Floyd Mayweather Jr. does prefer 8 oz gloves, but since this fight is taking place at Jr Middleweight, I believe they are wearing 10 oz gloves. Saul Alvarez said that they are using 10 oz gloves.
10 oz
floyd always wears extra fluffy gloves called grant to protect his brittle hands juiced w/ xylo
at jr.mid.... it will be a 10 oz super fluffy grant to soften the punches so a weight-drained-no-stamina canelo wont be able to hurt him the whole night.
floyd always wants it gentle...
I'd say 8.
I'm aware that Mayweather prefers 8 oz gloves but in his Jr Middleweight clash with Miguel Cotto he wore 10 oz gloves.
