Product Description DISTANCE + SOFT FEELSoft golf balls feel great. Hard golf balls go far. But youve never played a ball thats both soft and hard. Until now. We start with the core of the core. Then, we add the layers. Thousands of them. Until weve built a core thats firm enough to deliver the explosive distance you expect, yet soft enough for the feel youve always wanted in a tour ball. With its gradual transition from soft inner core to firm outer edge, Fast Layer behaves like a core with thousands of layers, giving you distance and soft feel without compromise. SPIN REVOLUTIONALIZEDIf you really want to score low, you need spin. A lot of spin. So we added Se RM (Slide Ring Material). This extremely resilient urethane cover uses Moveable Polymer Cross-Linking to greatly enhance spin. With molecular bonds that stretch but dont break, Se RM gives you a softer cover that actually digs into your club grooves at impact. That extra bite means more friction, which leads to dramatically more spin, and ultimately, unmatched stopping power around the green. MAX DISTANCEZ-STAR XV provides incredible spin, feel, and control, but where it really shines is DISTANCE. Its dual core construction makes every tee shot go farther and every green a club closer.
