Abstract: A golf ball including a core; an inner cover layer formed from a thermoplastic composition and having a thickness of about 0.005 inches to 0.40 inches and a surface hardness of about 60 Shore D or greater; and an outer cover layer formed from a thermoset material and having a thickness of about 0.01 inches to 0.05 inches and a surface hardness of about 60 Shore D or less. The thermoplastic composition has a first melt flow index at 280° C. under a 10-kg load of less than about 35 g/10 min and a second melt flow index at 265° C. under a 5-kg load of less than about 10 g/10 min.
