Our most advanced fairway wood ever, the 4DX Fairway Wood uses a super thin 0.4mm titanium crown to create an easy to hit club with a penetrating ball flight that lands softly.  By reducing weight in the crown, we were able to incorporate our patented XW inserts into the design to help control direction and trajectory and create a deeper face with a large sweet spot. Ultra-thinTitanium Crown Brazing an ultra-thin 0.4mm titanium crown reduces the weight in the crown, freeing up weight to be placed where you need it most – in the heel and toe to maximize MOI for greater stability and forgiveness. XW Inserts Our XW Inserts are the most sophisticated weight placement technology in the game.  The polymer insert helps dampen vibration while the 16 grams of weight help with directional control without relying on bulky screws that have a harsh feel at impact. Deep Face The deeper face has the largest sweet spot on a fairway wood we’ve ever created.  The deep face helps reduce spin to promote a lower, more penetrating ball flight.
