The Acer XDS hybrid iron set is designed for mid and higher handicapped golfers to help them excel on the course and gain confidence in their skills. The hollow-bodied construction increased the MOI providing more forgiveness than a traditional cavity back design, while the thin, variable thickness cup-face construction allows the face to flex to increase ball speed and maximize distance. The thinner face also frees up weight that is moved low and rearward for increased trajectory and softer landings on the green. The set takes on a progressive look and shape to give golfers more assistance where it is needed most.
