The Callaway Epic Flash driver features a new Callaway technology called Flash Face for significant ball speed and longer distances. Flash Face�s unique, internal mapping consists of dozens of subtle ripples flowing from heel to toe that work together to elevate COR in the face�s center region. The result is a significant ball speed boost for noticeable distance when solid contact is made. The Epic Flash also features a crown with new lightweight T2C triaxial carbon fabric which allows weight to be redistributed within the head to raise MOI for exceptional forgiveness on off-center hits. The sliding 16-gram weight gives golfers the power to easily promote draws, fades or a straighter flight.
