The Mizuno MX-200 irons feature Y-tune technology, which are an added benefit to the game improvement irons. This Y-tune technology extends and expands the sweet spot area of the clubface towards the toe to deliver incredible forgiveness on mis-hits. However, don't forget these irons keep the same Grain Flow Forged feel of many other Mizuno irons. The slightly larger, thicker club head lowers the CG and delivers a high, easy launch. Let Y-tune technology and Mizuno take control of your game so you can start shooting the lowest scores of your life.
