In addition to its PhD advanced dimple design and Nano Tech core, the Wilson Staff Px3 golf ball features a resilient Dupont HPF Mantle Layer which delivers increased velocity off the tee and higher spin rates on full iron shots. The PhD advanced dimple design has 312 flat-bottomed, shallow dimples (Pan Head) to rip through the air to create a more stable, high trajectory flight. The Nano-Tech core of the Wilson Staff Px3 golf ball has Nano particles infused into the rubber chemistry produce an extremely lively but soft inner core. The HPF Performance mantle layer fuels maximum acceleration off the club face and generates higher spin rates.
