Chrome Soft I the only ball that has the SoftFast Core with low compression and the Tour Urethane Cover.
The Callaway Chrome Soft balls have been revealed and looks set to build on the success of the original Chromesoft models. For the Callaway Chrome Soft ball a new Graphene Dual SoftFast Core is undoubtedly the headline change. It sees graphene a material stronger than diamond infused into the outer core. By using a stronger material, the outer core could be made thinner, which in turn allows for a larger, but still soft, inner core. This larger inner core allowed Callaway to enhance the ball's speed and reduce long game spin for more distance, while retaining the soft feel benefits of the original Chrome Soft balls.
