Hi.Per Pro Baseballs are designed and built to maximize both ball durability and ball flight accuracy when used with any baseball training machine. Equipped with a premium full-grain leather cover and Low-profile high-tensile-strength accu-seams, made from Kevlar, the Hi.Per Pro is the highest performing leather flat seam baseball. The low-profile seams reduce the aerodynamic drag of the baseball helping the ball achieve a more accurate ball flight than a traditional baseball with higher seams. In addition, the high-tensile-strength Kevlar seam material maximizes the ball's durability and extends the lifespan of the baseball.
