Abstract
A golf ball includes a single solid core having a surface hardness and a geometric center hardness. The core has an outer diameter of about 1.5 to 1.62 inches. An outer cover layer formed from a polyurea or polyurethane has a first hardness, and an inner cover layer, disposed between the core and the outer cover, has a second hardness greater than the first hardness and within 5 Shore C of the core surface hardness. The geometric center hardness is about 64 to 85 Shore C, and the core surface hardness is greater than 85 Shore C and harder than the geometric center hardness by about 5 to 22 Shore C to define a positive hardness gradient.
