ABSTRACT:
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 50 and the inner core and outer core generally have a combined dual core compression of 50 or greater. 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.
