Rogue ST MAX Irons have refined game-improvement shaping and the strongest lofts in the Rogue ST family. They fit a wide range of golfers who want incredible speed, forgiveness, and all-around iron performance. Callaway combined high strength 450 steel with A.I. designed Flash Face Cup. This delivers more ball speed and better ball speed consistency. Callaway applied their new A.I. Face Optimization for Rogue ST MAX. It's unique for each model and loft to create spin rate consistency across the face. It creates high launch and COR plus a more controlled landing angle to help hold greens. The new precision tungsten weighting features up to 62g of high-density tungsten, a 260% increase over MAVRIK. This provides improved launch conditions and maximizes speed across the face. Callaway's patented urethane microspheres are now pushed further up the face in Rogue ST irons (up to the 6th groove) to enhance sound and deliver pure feel while maintaining fast ball speeds. Rogue ST MAX are Callaway's longest Rogue ST iron, with refined game-improvement shaping for golfers who want incredible speed, forgiveness, and all-around iron performance. If you would like to customize the shaft, grip or length, please include a request in the order comments / shipping notes section. Standard Callaway warranty applies.
