Features & Benefits
- Innovative floating PWR-Bridge weight design enables 30% more face flexion to deliver untethered distance. The weight is suspended in a soft polymer filler to tune acoustics and feel
- Forged PWRSHELL face insert delivers more flexibility across a larger area of the face for faster ball speed and higher launch
- H.O.T Face Technology uses artificial intelligence to design a variable thickness pattern that delivers more efficient speed and spin across the face
