Wood Bat Pro JM21

The JM21 is built to give a player total balance and absolute consistency in a wood bat. It offers smooth handling with a traditional knob along with tremendous density delivered through a smaller barrel. The JM21 is Marucci’s best training bat. Training with a smaller barrel and smaller sweet spot drastically improves the hitter’s hand-eye coordination. This shows when it is then time to pick up a larger-barreled aluminum bat.
