Rogue ST MAX OS Lite irons have a refined game-improvement shaping, with high launch, wide soles, and enhanced offset. The Lite version features more loft, lighter shafts and lighter swingweights to make these our highest launching, easiest to swing Rogue ST model. Callaway combined high strength 450 steel with A.I. designed Flash Face Cup, which delivers more ball speed and better ball speed consistency. Callaway applied their new A.I. Face Optimization to Rogue ST MAX OS LITE. It's unique for each model and loft to create spin rate consistency across the face. It delivers high launch and COR plus a more controlled landing angle to help hold greens. New precision tungsten weighting features up to 46g of high-density tungsten, a 188% increase over MAVRIK. This provides improved launch conditions and also maximizes speed across the face. 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. 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.
