The S159 is Ping's tour-inspired wedge, offered in 25 loft-and-grind combinations across six grinds, including the half-moon H grind and low-bounce B grind alongside the returning S, W, T and E grinds. Precision wheel-cut grooves are milled to different dimensions by loft: tightly spaced MicroMax grooves on the higher lofts for scoring shots, and a milled sidewall on the lower lofts for full-shot control. An investment-cast head with an elastomer insert delivers a solid, controlled feel.
