America's top-selling tennis ball is the result of 100 years of testing and perfecting. Penn Championship has earned its reputation as the best.

This ball offers consistent performance thanks to its controlled fiber release, which provides an even nap, and natural rubber, which gives a consistent feel and reduces shock. You can expect unparalleled consistency every time you step onto the court.

These tennis balls can be used on various court surfaces, including hard courts, indoor and outdoor clay courts, and high-altitude courts above 4,000 feet.

As the official ball of USTA Leagues, you can trust that Penn Championship is a high-quality, consistent ball. It's available in different felt types, including extra-duty felt, regular-duty felt, and extra-duty high-altitude felt, and is approved by both USTA and ITF.

The interlocked wool fiber ensures that these tennis balls will retain their performance for as long as possible.
