Two-piece solid golf ball

摘要

In a 2-piece solid golf ball comprising a solid core and a cover, the golf ball has a weight of 41-44.5 grams, the cover is formed of a thermoplastic resin having a Shore D hardness of 50-68 degrees, and the solid core has a surface hardness of 65-85 degrees and a center hardness of 60-80 degrees as measured by a JIS-C scale hardness meter, with the surface hardness>/= the center hardness+5. Despite a light weight, the golf ball is improved in flying distance and feel when hit at a relatively low head speed of 35-40 m/sec. The golf ball is thus appropriate for players of the beginner to middle rank.
