A thread-wound golf ball has a wound core consisting of a center with a diameter of 29-37 mm and a rubber thread layer with a thickness of 1.0-2.5 mm. A cover enclosing the wound core is of two-layer construction comprising a relatively soft inner cover layer and a relatively hard outer cover layer having a Shore D hardness of 55-65. The inner and outer cover layers combined have a thickness of 2.0-5.0 mm. This construction gives the golf ball an excellent scuff resistance when hit with an iron club, as well as an improved spin, feel, and flight performance upon a full shot with a driver.
