Apex 21 is a high-tech, high-performance hybrid that blends exceptional ball speed with our remarkable new Jailbreak A.I. Velocity Blades. In addition to all that speed, we’ve engineered exceptional ball flight control and adjustability into a stunning players shape. This is a versatile, high performance hybrid that can help a wide range of golfers. The Jailbreak A.I. Velocity Blades are engineered to increase vertical stiffness near the sole of the club, creating more speed low on the face where players often mishit their hybrids. These blades allow the Face Cup to flex on the crown to promote better spin rate consistency, and the bars are spread to enhance torsional stiffness, leading to more forgiveness all across the face.
