The JPX ONE Fairways introduce a re-engineered CORTECH Chamber that strategically varies the internal gap between the sole and chamber wall. This geometry increases face flexion towards the toe and heel, amplifying energy transfer across the hitting surface without compromising central performance.Each head features a wrap-around composite crown that saves critical grams high in the structure, lowering the centre of gravity for higher launch and reduced spin. A multi-thickness MAS1C steel face ensures peak COR performance, while the all-new Speed Bevel sole refines turf interaction, producing cleaner strikes and more consistent ball speed from a variety of lies.
