The STIGA Genesis II S is an updated version of the original STIGA Genesis S. The STIGA Genesis II comes in two types, S and M. The S version being softer and the M being a harder version. The Genesis II uses the OCS technology from Sweden and Japan and a tacky top sheet from China. The new sticky surface has been specially developed for the plastic ball for maximum spin. The Genesis II S is also sustainably engineered to increase the durability and life expectancy of the rubber. The soft sponge produces a clear sound and incredible spin and touch play.
