Abstract
The present invention is directed towards a multi-layer golf ball which comprises a core, a cover layer, and a mantle layer disposed between the core and cover layer. The core has a PGA compression less than about 70, the mantle layer has a flexural modulus of less than about 10,000 psi, and the cover layer has a flexural modulus greater than about 75,000 psi.
