USA Boxing Approved and Approved for use in Canada - Master’s Competition Gloves feature Injected Molded Foam, which distributes shock more efficiently than traditional padding techniques. Injected Molded Foam insures an anatomically correct fit because it is actually created from a mold of a fist. This single sheet of 2 1/2” thick foam is more durable and absorbent than layered-foam padding systems. The gloves are 16 oz. with an attached thumb, a hook-and-loop closure and a nylon, pull-over sleeve for added safety.
