New proprietary Ionomer blend creates more efficient energy transfer from the Dual SoftFast Core for faster ball speed; The compounded additives improve consistency and durability, and the stiff mantle allows for ideal spin on wedge shots Thinner, more resilient cover promotes increased ball speed, and generates lower spin on full shots while maintaining high spin and soft feel around the green. Reduces drag for increased overall distance, with a higher ball flight for optimum trajectory.
