The official ball of USTA League Tennis and approved by the ITF and USTA, this regular-duty felt ball will maintain a dependable feel and bounce on the court. Featuring a controlled fiber release, the ball will remain consistent with every serve, volley, and hit. The natural rubber construction also reduces shock when the ball is hit. Surrounded by interlocked wool fiber for long wear and deep elastic seams reduce the potential for cracking too. Available in cans of 3, the balls are perfect for use on all surfaces.
