Abstract
Disclosed herein is a golf ball with a multi-layer cover. The golf ball has a core, an inner cover layer, an intermediate cover layer, and an outer cover layer, each cover layer having a different hardness than each adjacent cover layer. The sum of the thickness of the inner cover layer, intermediate cover layer and outer cover layer is 0.05-0.50 inches. A method for making the golf ball also is disclosed.
Claims6
A golf ball, comprising:
- a solid or wound core,
- and a multi-layer cover having at least three separate and distinct layers, said multi-layer cover comprising
- an inner cover layer formed around the core,
- an intermediate cover layer formed around the inner cover layer, and
- an outer cover layer formed around the intermediate cover layer, each cover layer having a different Shore D hardness than each adjacent cover layer, the intermediate layer having a Shore D hardness softer than the inner cover layer and harder than the outer cover layer.
