Abstract
The present invention is directed towards a multi-layered core golf ball that comprises a center, a cover and at least two core layers formed around the center to create an inner ball, wherein the outermost core layer is relatively stiff and hard relative to the center. One outermost core layer is heavily filled with a density increasing material and at least one core layer functions as a moisture vapor barrier. One core layer may serve to provide all the functions in a single layer.
