A straight bias driver with excellent stability from off center hits. Similar in look and character to the previous ST-Z. Boosted by the CORTECH Chamber to be faster from the face, spin less and deliver an incredible, solid sensation at impact.
Mizunos CORTECH Chamber encases a 3 gram stainless steel weight with elastomeric TPU taking stress from the clubface and creating an additional source of energy.
Toe Side Composite with shorter CG to shaft axis distance.
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.
