Abstract

A golf ball, comprising: a core; an inner cover layer formed over the core, the inner cover layer having a Shore D hardness of at least 60 as measured on the curved surface thereof, and an outer cover layer formed over the inner cover layer, the outer cover layer having a Shore D hardness of no more than 53 as measured on the curved surface thereof, at least one of the inner and outer cover layers comprising at least one member selected from the group consisting of polycarbonates, reaction-injection-molded polyurethanes, and styrene-butadiene elastomers, the golf ball having a PGA compression of 100 or less and a coefficient of restitution of at least 0.750.
