Rogue ST MAX are Callaway’s longest iron ever, with refined game-improvement shaping for golfers who want incredible speed, forgiveness, and all-around iron performance. For the first time in the industry, they’ve combined high strength 450 steel with our A.I. designed Flash Face Cup. This delivers more ball speed and better ball speed consistency. They’ve applied our 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.
