• New face curvature w/corrective face angle on off-center hits, to reduce side spin & deliver straighter shots. Provides more loft in high-toe & less loft in low-heel for more consistent spin
• Hammerhead slot: the reinforced outer portions of the slot allow for a lighter, more flexible face, resulting in a larger sweet spot
• The flexible center slot increases ball speed on low shots and lowers unwanted spin
• GEOCOUSTIC: Shaped for a solid and explosive sound. Reduced sole volume enables a larger, more forgiving face.
• The two-tone crown cosmetics have been altered to make the face angle appear more open, resulting in a more closed face at impact. 41 grams of weight have been moved heel-ward to deliver draw bias

The new M4 d-type driver combines the new twist face and Hammerhead Slot with innovative draw-biased features to provide a performance prescription that many golfers can benefit from.
