Multi-layer golf ball

摘要

Multi-layer golf balls having a relatively hard outer core surrounding a relatively soft, low compression inner core are provided. The inner core generally has a compression of less than 70. The outer core generally has a Shore C hardness of 80 or greater. A cover, which can be a single-, dual-, or multi-layer cover, is provided to surround the outer core. A moisture barrier layer is optionally provided between the outer core and the cover. The moisture vapor transmission rate of the moisture barrier layer is preferably less than the moisture vapor transmission rate of the cover.

1. A three-layer golf ball consisting essentially of:
an inner core layer having a compression of less than 70 and a Shore C hardness of less than 80; an outer core layer having a Shore C hardness of 80 or greater and a specific gravity of 1.11 or greater; and a single-layer cover; wherein the hardness of the inner core layer is less than the hardness of the outer core layer and wherein the specific gravity of the outer core layer is greater than or equal to the specific gravity of the inner core layer.
