Premium Impact Baseballs are constructed from durable, dent-resistant material, making them an ideal training ball for all players who want to add power to their swing. The durable build will withstand hit after hit, season after season. Premium Impact Baseballs are also official baseball size and feature an exterior texture for more accurate throwing. The bright yellow, high-visibility color helps players track the ball flight to improve their hand-eye coordination, and the ball weight and density provides instant feedback on contact. Coaches and players can use these practice balls all year round – they’re perfect for training drills both indoors and outdoors, and the limited flight capabilities make for easy retrieval. Premium Impact Baseballs come with a 1-year warranty.
