The Callaway Diablo Octane Tour 13 Fairway Woods are constructed from stainless steel and are engineered to maximise power for the better player. Incorporating aggressive VFT technology that precisely alters the internal thickness of the face in each club to increase the sweet spot, the Diablo Octane Tour 13 is the ultimate in performance driven design. The Tour models are designed with a smaller profile than the Diablo Octane Fairway, and together with the traditional hosel, this increases workability with low, penetrating trajectories that are preferred by more accomplished players. The Diablo Octane Tour 13 comes fitted with a Diablo Octane Tour Fairway Graphite Shaft as standard.
