The Titleist Pro V1x golf ball features the Tour-validated technology and performance with a spherically tiled 332 dimple design and new and improved A.I.M. (Alignment Integrated Marking) side stamp. The Pro V1x is a four piece golf ball designed for golfers with swing speeds over 105 mph. With exceptional distance and a more consistent flight the Pro V1x new design stabilizes ball flight like never before. The ProV1x has a firmer feel, less spin, and a lower trajectory than that of the Pro V1.
