MEDIUM GRADIENT DUAL CORE GOLF BALL |
| 摘要 |
A golf ball includes an inner core layer having a first surface hardness and a geometric center hardness. The center hardness is less than the first surface hardness to define a first positive hardness gradient of about 1 to 12 Shore C. An outer core layer has a second surface hardness. A cover layer is formed over the outer core layer. The second outer surface hardness is greater than the geometric center hardness to define a second positive hardness gradient of about 12 to 22 Shore C. |

1. A golf ball comprising:
an inner core layer having a first surface hardness and a geometric center hardness, the center hardness being less than the first surface hardness to define a first positive hardness gradient of about 1 to 12 Shore C; an outer core layer having a second surface hardness; and a cover layer disposed about the outer core layer; wherein the second outer surface hardness is greater than the geometric center hardness to define a second positive hardness gradient of about 12 to 22 Shore C. |
