The only driver awarded 20 out of 20 stars in the 2019 Golf Digest Hot List. The Epic Flash Driver employs a new Flash Face Technology, created by Artificial Intelligence, to help golfers get more ball speed for more distance. New Flash Face Technology for Faster Ball Speed Callaway engineers used Artificial Intelligence and Machine Learning to create a radically different face design to promote faster ball speed in the center region of the face. Jailbreak Technology for Faster Ball Speed Internal Jailbreak bars stiffen and stabilize the crown and sole, placing more impact load on the face to promote faster ball speed. New T2C Triaxial Carbon Crown Material for Higher MOI A new lighter triaxial carbon fabric called T2C has a tighter weave; the weight it saves is redistributed within the head to raise MOI for exceptional forgiveness on off-center hits. Adjustable Perimeter Weighting for Ball Flight Control Sliding 16-gram weight gives golfers the power to easily promote draws, fades or a straighter flight.
