    Abstract: The present invention is directed towards a multilayer golf ball (1) which comprises a core (2), at least one cover layer (3), and one or more mantle layers (4) disposed between the core (2) and cover layer (3). The mantle layer (4) comprises thermoplastic co-polyether ester block copolymer, thermoplastic co-polyesther esther stock copolymer, dynamically vulcanized thermoplastic elastomer, functionally styrene butadiene elastomer, thermoplastic polyurethane, metallocene polymer or blends thereof, and thermoset materials and fillers, such as barium sulfate, zinc oxide, titanium dioxide or blends thereof. Further, the present invention is directed to a ball (1) having a core (2) having a compression less than 70, a mantle layer (4) having flexural modulus of less than 10,000 psi, a specific gravity of greater than about 1.2, and the cover (3) having a flexural modulus greater than 75,000 psi.
