This 20-pack contains 60 high-quality tennis balls (3 balls per can), making it an excellent value for regular players and tennis enthusiasts.

These balls feature Extra Duty felt specifically designed for use on hard courts. As the Official Ball of USTA League Tennis, Penn Championship balls are trusted by players at all levels. The controlled fiber release technology ensures a consistent nap throughout the ball's life, while the natural rubber core provides a consistent feel with reduced shock on impact.

Penn's interlocked wool fiber construction delivers longer wear and durability, and the deep-elastic seams help reduce cracking over time. These features combine to make Penn Championship the #1 selling tennis ball in America.
