The Titleist Pro V1X 2014 golf ball features the Tour-validated technology and performance with a spherically tiled 328 dimple design and new and improved A.I.M. (Alignment Integrated Marking) side stamp. The 2014 Pro V1X is a four piece golf ball designed for golfers with swing speeds from 106+ mph. With increased spin control and a more consistent flight the Pro V1X design stabilizes ball flight like never before. The ProV1X has a firmer feel, lower spin rate, and a lower trajectory than that of the Pro V1.
