Patent ID: 7357734

Claim:
A golf ball comprising: a core having a diameter of 0.5 inches to 1.3 inches, a compression of about 45 or less, and a coefficient of restitution of 0.770 to 0.810; a cast polyurea cover having a hardness of about 60 Shore D to about 64 Shore D; and an intermediate layer disposed between the core and the cover and having a thickness of 0.17 inches or greater, the intermediate layer and the core being formed from a composition comprising a highly-neutralized thermoplastic material comprising an ethylene, α,β-ethylenically unsaturated C 3-8 carboxylic acid copolymer(s), a fatty acid salt, and a sufficient amount of a cation source to increase the level of neutralization of all the acid moieties to 100%; wherein a combination of the core and the intermediate layer results in a compression of 70 to 100, and the golf ball has a coefficient of restitution of 0.805 to 0.820 when measured at an incoming velocity of 125 ft/s and greater than 0.75 when measured at an incoming velocity of 160 ft/s, and a compression of 75 to 105.
