Abstract
A high CoR golf ball having predetermined moment of inertia is provided. A portion of the golf ball preferably contains substantially no filler, which contributes to the increased resilience of the ball. In accordance to one aspect of the invention, the portion with substantially no filler is the core of the ball. The remaining portions of the ball preferably contribute to the moment of inertia of the ball.
Claims30
A golf ball comprising
- a thin dense layer encasing a core, wherein the thin dense layer is encased by a cover, wherein the thin dense layer has a specific gravity of greater than 1.5 and a thickness from about 0.001 to about 0.050;
- and
- wherein the core is a non-wound core having a specific gravity of less than about 0.9 and less than the specific gravity of the thin dense layer, a diameter from about 1.54 to about 1.64 inches and wherein the core has substantially no filler
- wherein the thin dense layer comprises a densified loaded film.
