Abstract

A golf ball comprising a core comprising an inner core center and an outer core layer disposed over the inner core center. The inner core center has a deflection of greater than 0.210 inch under a load of 100 kilograms, and the entire the core has a deflection ranging from 0.130 inch to 0.105 inch under a load of 100 kilograms. A mantle layer is disposed over the core and a cover is disposed over the mantle.

Claims (14)

1. A golf ball comprising:

a core comprising an inner core center and an outer core layer disposed over the inner core center, the inner core center comprising a polybutadiene material and having a deflection of greater than 0.210 inch under a load of 100 kilograms, wherein the core has a deflection ranging from 0.130 inch to 0.105 inch under a load of 100 kilograms, wherein the core has a mass ranging from 25 grams to 40 grams, wherein the core has a diameter ranging from 1.40 inches to 1.64 inches;

a mantle layer disposed over the core, the mantle layer having a thickness ranging from 0.030 inch to 0.075 inch; and

a cover disposed over the mantle, the cover having a thickness ranging from 0.015 inch to 0.030;

wherein the golf ball has a diameter ranging from 1.65 inches to 1.685 inches.

2. The golf ball according to claim 1 wherein the mantle layer is composed of a material having a plaque Shore D hardness ranging from 44 to 50.

3. The golf ball according to claim 1 wherein the golf ball has a coefficient of restitution greater than 0.79.

4. A golf ball comprising:

a core comprising an inner core center and an outer core layer disposed over the inner core center, the inner core center comprising a polybutadiene material and having a deflection of greater than 0.210 inch under a load of 100 kilograms, the outer core comprising a polybutadiene material, wherein the core has a deflection ranging from 0.130 inch to 0.105 inch under a load of 100 kilograms, wherein the core has a mass ranging from 25 grams to 40 grams, wherein the core has a diameter ranging from 1.40 inches to 1.64 inches;

a mantle layer disposed over the core, the mantle layer composed of material having a plaque Shore D hardness ranging from 44 to 50; and

a cover disposed over the mantle, the cover composed of a material having a plaque Shore D hardness ranging from 50 to 62;

wherein the golf ball has a diameter ranging from 1.65 inches to 1.685 inches.

5. The golf ball according to claim 4 wherein the inner core has PGA compression less than 50.

6. The golf ball according to claim 4 wherein the mantle has a thickness ranging from 0.030 inch to 0.075 inch.
