The revolutionary new Srixon HR-X 333 features an entirely new cover material called Rabalon HR - an elastomer that is 65% more resilient than urethane. This soft and resilient material is combined with a proprietary highly elastic rubber mid-layer to deliver blistering velocity off the tee. The HR-X 333 features a unique and proprietary, seamless 333 dimple design - the world's first odd-numbered dimple pattern. These aerodynamics are designed to optimize the ball's low velocity lift for greater carry and a shallow angle of descent for greater roll. The soft Rabalon HR cover produces the ideal amount of approach iron spin and pinpoint distance control while delicate greenside shots land softly and stop quickly.
