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.
