Gloves

[Redd Foxx]

I have a pair of horse hair ones for display and they're pretty uncomfortable compared to my foam ones. I think the mainstream companies lean towards the foam ones.

First, they're not a mainstream company. They produce a relatively small amount.
Elvis Grant himself has said that they use "horse hair" in their gloves. I still believe it is a blend, but the ones GGG, Kov, Hopkins, etc use are referred to as "horse hair" Grants, while Floyd, Vitali, etc used either a blend or primarily orthopedic foam. Their training gloves seem to have a blend.

Even Cletos are a blend.
