The light weight and contoured grip of these mitts are what separates them from other curved mitts. They weigh in at just 8 oz. and offer a softer, more contoured padding in the hand compartment. Together those features give trainers a better grip on the mitts so they can concentrate on their movements freely. The whole mitt is constructed of genuine leather and the leather strap is padded for additional wrist comfort and a more secure closure. The strap is also easily adjustable for the best possible fit.
