Abstract: An improved golf ball having a thread-wound central core and an outer cover is provided. The outer cover is composed of a composition comprising (a) at least one ionomer which is a copolymer of at least one alpha -olefin and at least one alpha , beta -unsaturated carboxylic acid to which copolymer at least one metal ion selected from the group consisting of monovalent, divalent and trivalent metal ions is added and (b) at least one polyester elastomer, the content, in said composition, of said polyester elastomer being 50% by weight or less. This golf ball has excellent cutting resistance, "click" characteristics and impact resilience.
