The All-Star Anvil catcher's mitt is a multi-purpose trainer that uses added weight to improve receiving and transfer skills. Starting with the game's most popular 33.5" pattern, over 2lbs. of weight is evenly added to the thumb and pinky pads. This version of "weight training" helps strengthen those, hard-to-get-to small muscles that help with receiving pitches quietly and speeding up transfer times. - 33.5 Inch Catcher's Training Model - Closed web - Designed for training purposes only - Weighted design
