From the little leagues to the pros, you will have the best equipment to improve your game with the Rukket Sports 5 x 5 Baseball/Softball Net with 3 Weighted Balls and Strike Zone Target. The PUREPOWER weighted training balls are designed to help develop muscle memory for powerful throws and swings, and the design helps you realize if your swing is perfect or not, as the balls will just wobble and fall to the ground if you hit just a little off center. The bucket allows you to store and transport the balls wherever you go to practice.
