Abstract:
A golf ball comprising a core and a cover of at least two layers around the core, the cover layers including the outermost layer which is formed with a plurality of dimples, whereinsaid core has a hardness corresponding to a deflection of 3.0 to 6.0 mm under a load of 100 kg, said cover outermost layer has a Shore D hardness of 51 to less than 58, the product (AÃ—B) of the Shore D hardness, represented by B, of said cover outermost layer multiplied by the Shore D hardness, represented by A, of a cover layer disposed inside and contiguous to said cover outermost layer is in the range of 1,500 to 4,000, the plurality of dimples include at least three types of dimples which are different in diameter and have an average diameter (AD) and an average depth (AP) wherein the ratio (AD/AP) of the average diameter to the average depth is from 21/1 to 28/1, and the overall dimple volume which is the sum of the volumes of all dimple spaces each defined below a plane circumscribed by a dimple edge is in the range of 270 to 350 mm3.
