This is Akira's ADR Premium iron set. The face is larger than XXIO, making it easier to hit with confidence. The face also has good repulsion, making the ball easy to launch and stop on the green. The strong loft provides good distance. The shafts are carbon, equivalent to S flex, and are a collaboration model with the shaft maker BIGTRAJECTORY CD80TOUR. The grips are Golf Pride Tour Wrap, which provide high grip and allow you to hit without gloves. Recommended for those looking for easy-to-hit irons, those who want distance irons, and those who want clubs that are not commonly used.
