Features & Benefits
AI-designed FLASH face SS22 optimizes even 3 elements of flight
The "ROGUE ST MAX FAST iron" uses the FLASH face SS22, which has a face cup structure designed exclusively for this model by AI. The FLASH face SS22 does not only take into consideration the improvement of the initial velocity of the ball and the hitting position of the target golfer as in the past. This time, AI designed and tested with a new algorithm that includes the combination of the three elements of flight, spin, launch angle, and initial velocity of the ball. It has been upgraded to a face that has been optimized for each model and target golfer.

Carpenter 450, a new material, is used for the face cup.
The ROGUE ST series was developed with the major goal of evolving every part, and the materials used in irons were also focused on. The face cup is made of high-strength carpenter 450 with higher resilience instead of the conventional 17-4 stainless steel. We are trying to improve the initial velocity of the ball not only in various technologies but also in terms of materials.

Place the Precision Tungsten weight on the toe side and move the center of gravity to the face center.
In the ROGUE ST iron series, a MIM tungsten weight named Precision Tungsten Weight is mounted on the lower part near the sole on the toe side. As a result, the center of gravity is located at the face center. Of course, it also contributes to lowering the center of gravity, and realizes the ease of getting a good flight distance even in the event of a miss hit and the ease of raising the ball.

Urethane microspheres that now cover a considerable area behind the face
In the ROGUE ST iron series, urethane microspheres are also built into the lower part of the back of the face. Callaway's unique technology that improves the feel at impact without hindering the deflection of the face
