Abstract

A golf ball including a core and a cover layer, wherein the golf ball has a weight of about 1.39 oz to about 1.62 oz, and at a Reynolds number of about 207,000 and a non-dimensional spin ratio of about 0.095, the golf ball has a lift-to-weight ratio of greater than about 1.7 and a drag-to-weight ratio of greater than about 2.7.

Claims

1. A golf ball comprising:

a core; and

a cover layer;

wherein the golf ball has a weight of about 1.39 oz to about 1.62 oz, and at a Reynolds number of about 230,000 and a non-dimensional spin ratio of about 0.085, the golf ball has a lift-to-weight ratio of greater than about 2.1 and a drag-to-weight ratio of greater than about 3.0.

2. The golf ball of claim 1, wherein the golf ball has a coefficient of restitution of about 0.550 to 0.785.

3. The golf ball of claim 2, wherein the coefficient of restitution is about 0.600 to 0.780.
