Nike GL0680-701 RZN White features a lighter RZN core and heavier outer layers that result in the highest levels of MOI for more stable ball flight, especially in crosswinds. RZN is 10 percent lighter than conventional rubber. There is seamless dimple aerodynamics that are designed to reduce drag and optimize flight trajectory. The soft top coatings feature increased greenside spin and control. These balls are distance oriented with a 3-piece ionomer. Faster RZN core for greater distance. Lower driver spin for longer carry.
