The Srixon Z-Star X golf ball is firmer than the Z-Star and is made of an tremendously thin urethane cover, a highly durable Energetic Gradient Growth Core, an ionomer mid-layer, and a 324 dimple design with Invisiseam technology.

It is a high-performance multi-layer ball with a low compression and very soft feel, and has been developed to maximize energy shift to the ball for more distance. It is intended for club head speeds exceeding 106mph.
