M4 Iron Sets for Strength Training

The Key Performance Features

Ultra-Thin Leading Edge and Speed Pocket

The IRG-M4 5-P,A/Rh R irons feature an ultra-thin leading edge that works in conjunction with the Speed Pocket. This innovative design significantly enhances speed on low-face shots, ensuring every swing is optimized for optimal performance.

Enhanced Forgiveness with Weight Optimization

Optimized heel and toe weighting boost MOI (Moments of Inertia), resulting in increased forgiveness. This means you'll enjoy a smoother swing and more consistency, even off the sweet spot.

Fluted Hosel and 360° Undercut

The fluted hosel and 360° undercut design redistribute mass low in the clubhead, increasing launch distance and consistency. This innovative feature ensures your shots fly farther and more predictably.

Revolutionary RIBCOR Technology

The IRG-M4 5-P,A/Rh R irons are equipped with RIBCOR technology, a revolutionary innovation designed to help you hit the ball LONGER, HIGHER, and STRAIGHTER. RIBCOR localizes face flexibility, transferring more energy to the ball and increasing ball speed.
