Lightweight Performance Golf Balls

Abstract

The present invention is directed to a golf ball with a core and a cover layer surrounding the core. The golf ball preferably has a weight between about 1.45 ounces and about 1.57 ounces and the core preferably has a diameter of greater than about 1.58 inches. Thus, forming a lightweight golf ball with an oversize core. In a ball with a thermoplastic cover, the core preferably has a diameter of greater than 1.61 inches. In a ball with a thermoset cover, the core preferably has a diameter of greater than 1.58 inches. This golf ball is specifically designed to optimize its play characteristics for low swing speed players. The golf ball may further include an intermediate layer disposed between the core and the cover.

1 . A golf ball comprising: 
 (a) a core having a diameter greater than 1.58 inches; and    (b) a cover layer surrounding the core, said cover layer is formed of a light stable polyurethane or light stable polyurea;    (c) wherein the golf ball has a weight between about 1.45 ounces and about 1.57 ounces.    
   
   
       2 . The golf ball of  claim 1 , further including an intermediate layer disposed between the core and the cover layer, said intermediate layer being a moisture barrier layer.  
   
   
       3 . The golf ball of  claim 2 , wherein the moisture barrier layer is formed of an ionomer.  
   
   
       4 . The golf ball of  claim 2 , wherein said moisture barrier layer is formed from a thermoset material having a flexural modulus of about 500 psi to about 45,000 psi.
