The Nike RZN White golf balls offer distance performance for golfers with moderate-lower swing speeds who are looking for longer carry. Featuring Speedlock Technology, the interlocking RZN core design delivers more energy between layers for faster ball speed and longer distance. RZN (Resin) is a lighter, faster material designed for longer distance and a more consistent, stable ball flight. Perimeter weighting made possible by the lighter RZN core and heavier outer layers results in the highest levels of MOI for more stable ball flight, especially in crosswinds. RZN is 10% lighter than conventional rubber. Seamless dimple aerodynamics reduces drag and optimizes flight trajectory. The soft top coatings increases greenside spin and control. This may contain a mixture of different year models.
