ABSTRACT:
A golf ball comprising a core and a multilayer cover including at least a cover inner layer and a cover outer layer is characterized in that the core has a hardness corresponding to a compressive deflection amount of at least 3.5 mm when the load applied thereto is increased from an initial load of 10 kgf to a final load of 130 kgf, the cover outer layer is made of a resin composition having organic short fibers incorporated therein, the resin composition has a melt flow rate of at least 3 as measured according to JIS K7210, the cover outer layer has a Shore D hardness of at least 55 and is harder than the cover inner layer, and the cover outer layer has a gage of up to 1.4 mm. The golf ball has a soft feel, offers superior flight performance to even those golf players with a low head speed of 35 m/s or less, and is improved in durability to repeated impact and moldability.
