Claim:
A golf ball comprising: a core comprising a partially- or fully-neutralized ionomer, and having a diameter of about 1.40 inches or less, a compression of about 80 or less; and a coefficient of restitution of about 0.770 or greater when measured at an incoming velocity of 125 ft/s; a cover having a thickness of about 0.1 inches or greater and being formed from a composition comprising polyureas, polyurethane-ureas, or polyurea-urethanes; and an inner cover layer disposed between the core and the cover, the inner cover layer comprising an ionomeric material; wherein a combination of the core and the cover results in a compression of from about 75 to about 100, and the golf ball has a coefficient of restitution of about 0.810 or greater when measured at an incoming velocity of 125 ft/s.
