High performance golf ball having a reduced distance

Abstract

A golf ball comprising a core comprising from about 25 to 75 parts of butyl or halobutyl rubber and having a coefficient of restitution of 0.683 to 0.750 and a compression of less than about 60; an inner cover layer comprising an ionomer and having a Shore D hardness of at least about 60; and an outer cover layer comprising a polyurethane or polyurea having a Shore D hardness of less than about 55; wherein the golf ball has a dimple coverage of 55% to 75%, a coefficient of restitution of 0.696 to 0.775, and an Atti compression of at least about 80.

AI Technical Summary

Benefits of technology

[0013]The present invention is directed to a high performance golf ball having a reduced overall distance while maintaining the appearance of a high performance trajectory.

Problems solved by technology

The '485 patent theorizes that about 40% of the reduction in distance is attributable to the inefficient design, and about 60% is attributable to the low resilient ball composition.

Range balls, however, do not have the desirable feel or trajectory of high performance balls.

Further, the art does not suggest a way to fine-tune the distance of high performance golf balls to adhere to a shorter USGA maximum distance, while maintaining the appearance of a high performance trajectory.
