The Power Stick from SKLZ is an overload training bat that is 30" long and weighs 30 oz. This narrow-diameter, overload strength training bat helps to build batting-specific muscles - especially the shoulders, arms and hands. With 30 oz. of weight focused
into a narrow diameter barrel, players will notice better bat speed and
power during games. The narrow diameter shaft trains eyes to focus on the ball and develop better hand-eye coordination.
This product also works great in conjunction with the SKLZ Quick Stick Underload Training Bat
