This is one of the softest types of golf balls you'll find. The extra middle cover layer that it posses in comparison with the three-piece ball, enables it to cover a longer distance as well as giving it a mid iron spin. The shell or outermost later has around three hundred to four hundred dimples, is made from Urethane and is very soft to the touch. The dimples on a gold ball help minimize the surface area of the ball that is exposed to air, which in turn reduces the frictional air forces, or drag on it, thereby letting it cover a longer distance. A golf ball with dimples would cover a much larger area than one without any.
