Mizuno ST-X 230 DRIVER - HELIUM NANO 40 - 12 - A FLEX

A more rounded, deeper profile with weight located closer to the hosel - means slightly higher spinning and draw biased for the majority, but more workable for many elite players (especially in lower lofts). Natural drawers of the ball may find more ball speed from the ST-X. Boosted by the CORTECH Chamber to be faster from the face, spin less and deliver an incredible, solid sensation at impact. THROUGH SLOT PROVIDES ADDITIONAL CORAREA BY PROVIDING SOLE FLEX TPU MATERIAL ALLOWS SOLE FLEXURE FOR FACE STRESS REDUCTION TPU MATERIAL PROVIDES SOUND TUNING/DAMPING FOR ENHANCED SOLID FEEL INSERTED STAINLESS STEEL WEIGHT, IDEALLY LOCATED FOR SPIN REDUCTION Mizuno’s CORTECH Chamber encases a 3 gram stainless steel weight with elastomeric TPU - taking stress from the clubface and creating an additional source of energy. Design focus is a combination of deeper CG and shorter CG distance for a balance of workability in both directions while providing higher MOI and mid/low spin.
