For the first time in the industry, we’ve combined high-strength 450 steel with our A.I. designed Flash Face Cup. We’ve also continued to push innovation through our patented Urethane Microspheres and have massively increased our Precision Tungsten Weighting. Callaway 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.
