Golf ball
摘要:
A solid golf ball comprising a core and a cover is provided. The core has a core hardness expressed by a distortion of 2.2-4.0 mm under a load of 100 kg. The core hardness divided by the ball hardness ranges from 1.0 to 1.3. The cover has a thickness of 1.3-1.8 mm. The ball is improved in feel and spin while maintaining the flying distance inherent to solid golf balls.
