A golf ball including a core having a diameter of 0.5 inches to 1.4 inches, a compression of about 45 or less; and a coefficient of restitution of from 0.730 to 0.810; a cast polyurea cover; and an intermediate layer disposed between the core and the cover, the intermediate layer having a thickness of 0.11 inches or greater and being formed from a composition including a highly-neutralized acid polymer having a moisture vapor transmission rate of 8 gmil/100 in.sup.2/day or less; wherein a combination of the core and the intermediate layer results in a compression of from about 70 to about 100, and the golf ball has a coefficient of restitution of from 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 from 75 to 105.
