Soft Response is designed for moderate swing speed players with a new, softer core and a re-engineered ionomer cover for added greenside spin. The changes give you a softer ball with an overall 50 compression (versus a 60 compression rate in the previous generation). An added SpeedMantle™ layer in its 3-piece construction creates efficient energy transfer at impact, creating a softer ball that enhances feel and maintains both ball speed and distance.
