Abstract
A golf ball consisting of a multi-piece cover surrounding a core. The cover consists of a multi-sheet structure which includes at least three thin layers of thermoplastic with each layer having a thickness of no more than 0.030 inches. The hardness of the multi-sheet structure varies between adjacent layers so that the reaction of the ball varies depending upon the amount of deformation of the ball upon impact with a golf club. The method of manufacturing a golf ball includes producing a cover from a multi-layer member, with at least one layer having a thickness of no more than 0.030 inches.
