    摘要： In a solid golf ball comprising an elastic solid core and a resin cover, the cover has a JIS-C hardness of 50-85, and provided that the ball receives a spin rate S1 (rpm) in the dry state and a spin rate S2 (rpm) in the wet state when hit with a short iron having a loft of an 8-iron or greater, the percent spin retention: (S2/S1)×100 is at least 47%. The ball's spin susceptibility when hit with the short iron is not reduced in the dry state or fine weather, nor is noticeably reduced even in the wet state or rain weather. The ball has so high performance that the ball travels a distance as intended, immediately stops on the green, is easy to control and thus, suited for professional and amateur low-handicap golfers.

    摘要： Provided is a multi-piece solid golf ball, wherein an outer layer cover has a polyurethane based elastomer as a main component; a solid core surface Shore D hardness is 50 to 60, an inner layer cover Shore D hardness is 53 to 61, and an outer layer cover Shore D hardness is 52 to 58; an average surface Shore D hardness of the solid core and inner and outer layer covers is 53 to 58; a value obtained by dividing a thickness of the outer layer cover by a thickness of the inner layer cover is 0.48 to 1.00, and a total thickness of the outer and inner layer covers is 1.5 mm to 3.5 mm; and a dimple volume occupying ratio VR value is 0.66% to 0.85%. The golf ball is excellent in flight performance, feeling characteristic, and controllability, and is improved in scratch resistance and durability against hitting.
