摘要 |
In a wound golf ball comprising a solid center (1), thread rubber (2), and a cover (3), the cover has a multi-layer structure including an outer layer (4) and an inner layer (5) having a higher hardness than the outer layer. The outer layer (4) is 0.4-3.0 mm thick, and it is formed of a first ionomer resin having a Shore D hardness of 40 to 55. The inner layer is formed of a second ionomer resin having a Shore D hardness of 55 to 68. The difference in hardness between the first and second ionomer resins is at least 5 in Shore D hardness. The ball affords improved spin and durability.
