The Deluxe MiM Foam Sparring Glove is made of cowhide leather and 2.5 inches of MiM foam (machine injected molded foam) that provides superior protection for the knuckles. With attached padded thumbs, the soft poly/nylon lining is quick drying. The dual cross-directional strap system (where one strap is elasticated and covered by a second leather strap)provides the ultimate wrist support and striking performance.
