About this ball

The return of the Hot Line made waves with the Typhoon—but when bowlers needed more traction to handle increased oil volume, the answer was clear. Meet the Monsoon. Featuring Reactor™ Solid coverstock finished at 2000-grit Abralon®, it creates a larger footprint for added control and confidence on more oil. The Atmos A.I. Core delivers the ideal balance of length and continuation, producing a reliable motion at the breakpoint. Ideal for competitive bowlers seeking consistency and control, it’s also a great option for seniors and youth looking for high-performance technology in lighter weights.
