A large footprint, lower profile hybrid – engineered to deliver absolute straight line performance from across the clubface.
A high energy MAS1C steel face is enhanced by an expanded CORTECH Chamber, shifted closer to the clubface to increase both centre and off centre ball speeds. A speed bevel applied to the leading edge ensures that performance is equally impressive from tee and turf.
Weight located low and deep and an ultra-lightweight waffle crown combine to deliver an impressively straight, predictable ball flight.
"The ST MAX fairway and hybrid feel like they’re on tracks through impact. The heads are so stable that it’s actually very hard to work the ball if that’s your game. But if a high straight flight is ok – these are almost like cheating!"
