The Srixon Z-STAR X golf balls provide exceptional feel around the green and optimal distance off the tee. These high performance 3 piece golf balls have a lower compression, fly longer, and feel firmer than the Z-STAR. Z-STAR X golf balls have a slightly firmer feel for exceptional distance without sacrificing green-grabbing control. They feature an ultra-thin urethane cover, a high energy gradient growth core, and a new dimple configuration that maximizes performance. The Z-STAR X is ideal for golfers with swing speeds of 105 mph or higher, with spin tuned for extreme tour distance and exceptional stopping power on approach shots. The Z-STAR X is comparable to the Titleist Pro V1x, Nike One Tour D, and Callaway HX Tour golf balls.
