2-piece vs 3-piece vs 4-piece golf balls: how each is built

A golf ball is a core with layers around it, and "piece" counts the layers: a 2-piece ball has two, a 3-piece three, a 4-piece four. Here's how each build is put together, and where the two Thick balls fit.

• 2-layer. A solid core and a cover. Neither Thick ball is a 2-layer ball.
• 3-layer. Adds a middle layer between the core and the cover. Moon Shot, the one for most people. Three layers: a rubber core and a resin mantle. Urethane cover.
• 4-layer. Adds one more layer. Moon Shot Pro, the one that spins. Four-layer construction holds ball speed across swing speeds. Urethane cover.
