At the heart of the Wilson Staff Cortex Driver is Fast Cage Technology. Over 44% of the head has been replaced with lightweight carbon fiber, leaving a rigid titanium skeleton that provides structural stability and precise weight distribution for ultimate in adjustability. Fast Cage puts the weight where you want it, maximizing distance and optimizing spin for all swings. Wilson's longest-ever slide track provides a wide range of spin options. Moving the 8g weight toward the face adjusts the center of gravity for a low launching ball flight with maximum fairway rollout. Sliding the weight towards the rear of the driver creates higher ball flights and maximizes carry. The Cortex Driver comes standard with the 8g weight near the toe and the 2g weight near the heel. This provides a neutral distribution of weight. To obtain a draw setting, the 8g weight can easily be moved to the heel and the 2g to be inserted near the toe. The Fast-Fit hosel system allows players to dial in their preferred ball trajectory by fine tuning the loft with 6 unique loft settings in half-degree increments. Premium Fujikura ATMOS Tour Spec Shafts are available in three profiles with unique launch and spin to provide fitters with options for both tour players and amateur golfers. Similarities across the three shafts include keeping the handle flexes the same for feel, but adjusting the mid and tip sections for launch and spin to achieve desired results. The Atmos Black provides a very low launch and low spin. The Atmos Blue offers a mid-high launch with ample spin for maximum versatility and balanced performance. The Atmos Red has a softer tip profile which generates a high launch and high spin.
