Abstract
A four-piece solid golf ball construction is disclosed, including one or more core layers, an inner mantle layer, an outer mantle layer, and one or more cover layers. The inner mantle layer has a Shore D hardness in the range of 20 to 60, and the outer mantle layer has a Shore D hardness in the range of 40 to 80 and exceeding that of the inner mantle layer by at least 3. The solid golf ball provides a high spin rate when struck not only by a full 8-iron, but also by a soft pitching wedge, for short shots near a putting green.
