Callaway’s ST MAX OS hybrid, with industry-leading new jailbreak system for powerful distance. The ST MAX OS is built with an oversize head profile and draw bias weighting, for golfers looking for added confidence and all-around hybrid performance
A.I. Designed Jailbreak System
By applying Artificial Intelligence to the architecture of this new structure, the Jailbreak system works by spreading the batwings out to the perimeter. So as well as stiffening up the body, the new design allows the face to flex more. The result is exceptional ball speeds and added stability.
Callaway Golf has advanced its new face architecture across a more expansive area to deliver more forgiveness, launch and spin, to its already ultra-fast ball speed performance.
High Strength 455 Face Cup
The 455 steel is proprietary high strength steel to enhance flexibility, providing enhanced speed and spin consistency across the face.
Precision Tungsten Weighted
24 grams of additional tungsten weight delivers a more precise CG location in the fairway head, this enhances ball speed and improves launch. Complete with a sole construction to promote better turf interaction and versatility from a variety of different lies.
