Finished with a durable clear polyester coverstock, it blends legendary style with everyday functionality. Whether you're refining your spare game or stepping onto the lanes for the first time, this ball delivers the confidence of a legend with every roll.

The Hex Core is designed to enhance predictability for every type of bowler. From a beginner’s first ball to a touring professional’s go-to spare option, this proven design delivers consistent, reliable motion you can trust.
CLEAR POLYESTER COVERSTOCK — STRENGTH, DURABILITY, AND PREDICTABILITY
When a straight shot matters most, polyester is the answer. Engineered for minimal friction and maximum control, it ensures the ball holds its line and performs exactly as expected. On challenging patterns where hook can work against you, take the oil out of play and trust polyester to get the job done.
