A golf ball comprising:
- a core formed from a polymer composition comprising a blend of a diene rubber, a halogenated organosulfur compound, and a salt of a mono- or poly-unsaturated long chain organic acid;
- and
- a cover having a thickness of about 0.05 inches or less and comprising a polymer containing an acid group, an organic acid or a salt, and sufficient cation source, or a suitable base of the organic acid, to fully-neutralize the acid groups of the polymer;
- wherein the core comprises a center and an outer core layer and has an outer diameter of 1.590 inches to 1.610 inches;
- and the cover comprises an inner cover layer comprising the fully-neutralized polymer and an outer cover layer comprising polyurea, a polyura-urethane, or a polyurethane-urea.
