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 2 lbs. 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.
