ABSTRACT:
In a solid multi-piece golf ball comprising a solid core, a mantle, and a cover, the ratio of the compression of the mantle to the compression of the solid core is at least 0.98, and the difference in JIS-C hardness between the surface and the center of the solid core is at least 5. This construction and combination of features provide the ball with a good feel when hit with various types of golf clubs and improved distance when struck with a driver.
