Every September the toughest tournament in the world uses over 70,000 of the toughest tennis balls: Wilson U.S. Open balls. Since 1979, Wilson has been the only ball that has held the distinction of being the "Official Ball of the U.S. Open". Constructed of premium high-grade wool that is woven into a thicker, denser felt, the Wilson U.S. Open tennis ball is known for its superior playability, consistency and durability. The regular duty is best suited for clay and indoor courts as well.
Sanctioned for ITF and USTA tournaments
Note: Cases of balls ship separately via UPS Ground.
