DESC: Dimple in Dimple Aerodynamics:Unique aerodynamic surface maintains spin longer throughout flight, increasing aerodynamic efficiency by reducing drag to maximize distance for a wide range of swing speeds. Soft, Thin, More Durable Cover:Provides superior short-game spin and feel for great control around the greens with better durability.High-Resiliency Core with Better Feel:Generates outstanding distance while maintaining soft feel.DuPont HPF Mantle Layer:Increases ball speed and reduces spin off the driver to maximize distance.
