The Bownet Snap Back™ Training Balls are constructed to provide superior training for finding your optimal sweet spot. The twelve pack of baseball sized poly-flex balls are engineered to outlast thousands of hits from the lightest hitters to ball destroyers without leaving dents or cracks. The Snap Back™ design collapses after a hit, creates greater impact feedback and a longer period of kinetic transfer from bat to ball. Limited flight following a hit provides less time retrieving balls from across a field and more time for play. Heavier duty distributed weight makes throwing in the wind easy and greater accuracy can be built when thrown into the Big Mouth® Net (sold separately). Help train batting accuracy with the 9" sized balls that help to hone players' focus. With an impact absorption design and a durable, poly-flex material, the Snap Back balls are the ultimate training ball for softball, baseball, and tee-ball hitters.
