Design features include two-tone hemispheres and bright neon colors for improved visual tracking, plus hollow-hole or pop-back patterns (for example, 26-hole designs) that make spin and trajectory easier to observe.
These balls are described for batting practice, pitching, throwing and catching drills, warm-ups, use with nets or batting screens, indoor or outdoor training, and even pet training or general outdoor games.
