What Is The Difference Between A 2 Piece Golf Ball & A 3 Piece Ball?

Modern golf balls are made of separate layers of solid synthetic materials. Two-piece balls consist of only an inner core and a thin cover, while the more sophisticated three-piece design incorporates an additional layer. Three-layer balls provide better overall performance on a variety of shots.

Golf Ball Construction

Two-piece golf balls have an inner core and a tough outer cover made of a compound called an ionomer. The core makes up most of the overall volume and gives the ball most of its properties, while the cover affects the ball’s feel and durability. Three-piece balls use an additional concentric layer between the core and cover and usually have a soft urethane rubber cover.

Two-Piece Balls

Most two-piece balls have a single function that depends on the formulation of their core and cover. Distance balls like the Callaway Big Bertha have firm cores and thin hard covers. They are durable and spin very little so they tend to fly straight. Those with softer cores and covers like the Nike Power Distance Soft have better feel and give you more distance if you have a slower swing speed. Performance balls like the Titleist NXT Tour use a combination of a softer core for feel and a thin cover to increase distance. Two-piece balls sell for $15 to $30 a dozen, as of publication.

Three-Piece Balls

The additional layer of the three-piece ball allows it to perform better on different shots. The three layers cause the ball to react differently depending on the club you use. The ball’s very soft cover produces optimum feel and spin on shorter shots and the intermediate layer is soft enough to provide spin on iron shots. On drives and long iron shots when clubhead speed is highest, the middle layer compresses and the hard core takes over to deliver maximum distance and minimum spin. A dozen three-piece balls retail for $25 to $58 for the popular Titleist ProV1, as of publication.

Trade-Offs

Two-piece balls are cheaper and more durable than the urethane-covered three-layer balls and deliver adequate performance for most golfers. Three-piece balls usually have better feel and higher spin on shorter shots while still flying long and straight off the tee. You might not receive all of the benefits of the multilayer design unless your swing speed is close to that of a tour player. Players with swing speeds of less than 80 mph sometimes find that they achieve longer distance with a softer two-piece ball, and the green-side performance of some of these is quite good.
