A golf ball including a core having a compression of about 50 or less and a coefficient of restitution of 0.800 or greater, the core including a hollow, liquid, gel, or gas-filled center and an outer core layer; a thermoset polyurea cover having a hardness of 64 Shore D or less and a thickness of 0.02 inches to 0.1 inches; and an intermediate layer disposed between the core and the cover, the intermediate layer having a thickness of 0.110 inches or greater; wherein a combination of the core and the intermediate layer results in a compression of 60 or greater and the golf ball has a coefficient of restitution of 0.805 or greater 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.
