A new Exo-Cage design with super-light triaxial carbon in the Callaway Big Bertha Fusion woods is said to take forgiveness to a whole new level
Twelve years on from the original Fusion woods, Callaway has relaunched the franchise and turned to an aerospace-grade titanium exoskeleton called an Exo-Cage to bring it right up to date. This has been paired with a crown and sole made from triaxial carbon, a material that is over 65 per cent less dense than titanium and more than 35 per cent thinner than Callaway’s previous composite material.
