The Nike One RZN Golf Balls are ideal for the amateur player looking for more control and straighter shots. With a three-piece ionomer construction including a large resin core, these balls have a softer feel on impact. The benefits include a three-piece ionomer construction for true flight and durability and a soft resin core is lighter than rubber for maximum distance and high velocity. Steeper spin slope for lower driver spin, higher wedge spin. Highest levels of MOI for longer more controlled shots.
