A draw-biased carbon composite construction aided by a heel side sole weight. Built upon the 2nd generation of Mizuno's Forged SAT2041 Beta Ti face – for potent ball speeds and consistent performance over time. Slower swing speeds will benefit from the J-Spec – incorporating an incredibly lightweight 39g MFusion graphite shaft.
Expanded toe located carbon composite window, with heel located sole weight combine to produce a reliable draw bias.
Delivers an additional contribution to ball speed – especially low from the clubface.
Slightly deeper back portion and more upright visual lie angle.
4 degrees of loft adjustability to fine-tune look and trajectory.
“In testing, a lot of our tour players preferred the ST-X over the ST-Z for its deeper shape and slightly smaller profile. I’d recommend starting with an open mind and dropping the ST-X alongside the ST-Z in the address position. For a draw bias driver, it’s not going to be what most players expect.”
