High Draw Flight bias: Mizuno's X-Axis design with an ultra-light waffle crown and deep internal weighting encourage a high draw-biased flight.
High Ball Speed Face: At 1.8mm the ST-X 220 face is the thinnest and fastest face on any Mizuno hybrid.
Optimized Wave Sole: Hybrid specific design helps create higher ball speeds from low on the face to encourage use from the fairway.
Solid Feel: Research identifies and isolates vibration patterns that elite players associate with a preferred feel which engineers built into the clubhead.
