The Nike Lady SQ MachSpeed STR8-FIT Fairway Wood is a fairway metal wood designed to optimize aerodynamics throughout the swing and to deliver more clubhead speed than any previous fairway metal. Comprehensive aerodynamic engineering moves air faster across the sole, over the crown and around the skirt for incremental swing speed advances. By moving weight out and into the corners, Tour proven Square Technology delivers more stability through the turf. The ultr-thin face delivers hotter response and longer shots. The stock shaft is the SQ Proforce Axivcore by UST Mamiya.
