Callaway Epic Flash Sub Zero Fairway Woods combine groundbreaking new Flash Face Technology with precision shot-shaping for high swing speed players. Flash Face creates a new fairway wood face design and combines with a Forged Carpenter Steel Face Cup to promote increased ball speed for longer distance. Jailbreak Technology incorporates two internal bars that stiffen the body, placing more impact load on the face for fast ball speed. Adjustable Sole Weights (16g and 2g) can be positioned to adjust launch, spin and trajectory. New Optimist Hostel is shorter and lighter, and the saved weight is used to reposition the CG for easy launch and high, long-carrying flight.
