Golf ball with softer feel and high iron spin

1. A golf ball comprising:

(a) a core;

(b) an inner mantle layer adjacent to the core;

(c) an outer mantle layer adjacent to the inner mantle layer, wherein the outer mantle layer comprises a modified ionomer comprising acidic groups wherein 70 to 100 percent of the acidic groups are neutralized by a metal ion and the outer mantle layer has a material Shore D hardness of 45 to 75;

(d) an inner cover layer adjacent to the outer mantle layer, wherein the inner cover layer has a material Shore D hardness of 10 to 65 and comprises a polyether amide elastomer; and

(e) an outer cover layer adjacent to the inner cover layer, wherein the outer cover layer is selected from a thermoset polyurethane or a thermoset polyurea and the outer cover layer has a material Shore D hardness of 30 to 70,

wherein the inner cover layer has a material Shore D hardness that is at least 20 units less than the material Shore D hardness of the outer cover layer, and the inner cover layer has a thickness of less than or equal to 0.050 in; and

wherein the material Shore D hardness of the mantle layer adjacent the inner cover layer is at least 3 units greater than the material Shore D hardness of the inner cover layer.

2. The golf ball of claim 1 , wherein the inner cover layer has a thickness of less than or equal to 0.030 in.

3. The golf ball of claim 1 , wherein the inner cover layer has a thickness of less than or equal to 0.020 in.

4. The golf ball of claim 1 , wherein the mantle layer adjacent to the inner cover layer has a thickness of at least 0.030 in.

5. The golf ball of claim 1 , wherein the outer cover layer has a thickness of at least 0.020 in.

6. The golf ball of claim 1 , wherein the outer cover layer has a thickness of 0.025 to 0.065 in.

7. The golf ball of claim 1 , wherein the inner cover layer has a thickness of 0.005 to 0.025 in.
