Multi-layer core golf ball
First Claim
1. A golf ball comprising:
- an inner core having a compression of less than about 60;
at least one intermediate layer surrounding the inner core;
at least one outer core layer surrounding the intermediate layer, having a hardness of at least about 55 Shore D and a specific gravity greater than a specific gravity of the inner core; and
a cover surrounding the at least one outer core layer having a Shore D hardness of at least 60;
wherein at least one of the inner core, intermediate layer and outer core layer comprises a partially or fully neutralized ionomer;
wherein the inner core has a hardness less than a hardness of the at least one outer core layer; and
wherein a specific gravity of the cover is less than the specific gravity of the at least one outer core layer.

Abstract
A golf ball comprising: an inner core having a compression of less than about 60; at least one outer core layer (surrounding the inner core or an optional intermediate layer) having a hardness of at least about 55 Shore D and a specific gravity greater than a specific gravity of the inner core; and a cover surrounding the outer core layer; at least one of the inner core, intermediate layer and outer core layer comprising a partially or fully neutralized ionomer; and the inner core having a hardness less than a hardness of the at least one outer core layer. Additionally, either the cover has a Shore D hardness of at least 60 and a specific gravity less than the specific gravity of the at least one outer core layer, or the inner core comprises a partially or fully neutralized ionomer and a specific gravity less than 1.0.
