1. A golf ball comprising:
- a core;
a cover disposed about the core, consisting essentially of;
an inner cover layer formed from a first composition having a first hardness, a first thickness of about 0.01 inches to about 0.25 inches, and a first flexural modulus;
an outer cover layer disposed on the inner cover formed from a second composition having a second hardness, a second thickness, and a second flexural modulus, wherein the second hardness differs from the first hardness by about 5 points or less, wherein the second thickness is less than the first thickness and from about 0.005 inches to about 0.1 inches, and wherein the second flexural modulus is less than the first flexural modulus.
