The GroBat Jr™ is a small diameter bat, the length is 30" and weighs 19 oz.  It is designed to be used with the Personal Pitcher Wiffle balls. Hitting a small ball with a thin bat is proven to improve hand-eye coordination and confidence.

The GroBat Jr comes with a sweet spot pad, 1" removable choke up collar, and professional leather grip. When the ball hits the sweet spot pad, the hitter will hear a nice "pop" sound letting him know he crushed it. The 1" choke up collar will shorten the bat or help a hitter if he needs more bat control. A small bat hitting a small ball equals big results!
