The entire M4 series features Speed Pocket technology. It increases the club head's flexibility with a thinner sole that increases ball flight.
This technology increases the club speed and guarantees an optimal distance, even on shots taken too low on the club face.
GEOCOUSTIC TECHNOLOGY
The Geocoustic technology combines geometry and acoustics to optimise forgiveness, all while producing a powerful and pleasant sound upon impact.
The sole’s geometry also makes it possible to reduce the vibrations caused by the ball's impact.
