Callaway Rogue ST Pro Irons w/ Graphite Shafts Callaway are the #1 Irons in Golf because of our groundbreaking innovations that benefit golfers of all abilities. The new Rogue ST Irons are no exception. They’re breaking new ground through a high strength 450 A.I. Face Cup that’s never been seen before in the golf industry. They’ve also continued to push innovation through our patented Urethane Microspheres and have massively increased our precision tungsten weighting. Rogue ST Pro irons are designed for low-to-mid single digit handicap golfers. They feature all the best technologies of Rogue ST, in a hollow body construction and a compact players shape. More Ball Speed from the All-New High Strength 450 A.I. Designed Flash Face Cup An industry-first, Callaway combined high strength 450 steel with our A.I. designed Flash Face Cup. This delivers more ball speed and better ball speed consistency. New A.I. Face Optimization for Speed, Launch and Spin Callaway has 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. Precision Tungsten Weighting for Optimal Launch Our new precision tungsten weighting features up to 48g of highdensity tungsten, a 188% increase over MAVRIK. This provides improved launch conditions and also maximizes speed across the face. Patented Urethan Microspheres for Pure Feel Our 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.
