The GroBat™ is a small diameter bat 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 comes with a sweet spot pad, weight pack, 1″ removeable 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 weight pack is the key to having a bat that can grow with a player as the weight can change anywhere between 20oz to 31oz. The 1″ choke up collar will shorten the bat or help a hitter if he needs more bat control. Small bat hitting a small ball equals big results!
