Maximize your greenside spin and enjoy ample distance performance, all with exceptionally soft feel. Choose Z-STAR if finesse around the greens and pinpoint approach shots are your keys to record low scores. !!!!FASTLAYER CORE!!!! Soft at its center yet firm around its edge, FastLayer Core gives you speed and great feel so you can play with confidence and big distance. A special heat treatment bakes speed into the outer portions of the core yet leaves the center satisfyingly soft. And the transition from soft to firm happens gradually, giving you consistent performance shot-to-shot, club-to-club. !!!!URETHANE COVER & SPIN SKIN WITH SERM!!!! Every Z-STAR Series golf ball features an extra thin, thermoplastic urethane cover. For even more spin and control, we add our Spin Skin coating. This additional layer of urethane is only a few microns thick, but it uses Slide-Ring Material (SeRM) to increase friction and maximize spin on chips and pitches. !!!!338 SPEED DIMPLE PATTERN!!!! With their new, deeper dimensions, the redesigned 338 Speed Dimples on each Z-STAR Series golf ball punch through air for a penetrating launch. After launch, the dimples generate lift, driving the ball upward and maximizing glide distance during descent.
