Callaway X2 Hot Driver Callaway set out to create a driver better than the one played by the longest hitters in golf. To do that, they had to start fresh and change everything, and the results were not incremental. The X2 Hot Driver offers a new Hyper Speed Face, an improved head shape and construction, and new Advanced Adjustable Hosel technology. New Hyper Speed Face: Here's what you'll get from their fastest, thinnest, all-titanium driver face ever: faster ball speeds, a larger sweet spot, more forgiveness, and insane distance. Improved Head Shape and Construction: That means more ball speed and distance on shots hit not only in the center of the face, but on off-center hits as well. New Advanced Adjustable Hosel Technology: Increase or decrease your loft (+2 deg and -1 deg), and adjust to a Draw or Neutral directional bias, optimizing your launch, backspin, and dialing in your preferred shot shape. In just a few clicks, you'll be fit for maximizing your distance with more accuracy. Aldila Tour Shaft: This premium shaft delivers excellent feel and control and is designed to optimize launch conditions.
