Offset Hosel
Designed to provide a look that boosts confidence at address and provides greater workability, the offset hosel also assists in squaring the clubface at impact

VFT Technology
A new, aggressive advancement of our tried and true VFT technology provides increased ball speeds across the entire face. That means hotter distance with even more consistency.

Larger, high MOI clubhead
A larger, high MOI clubhead design creates greater stability at impact, increasing accuracy and performance, and offering maximum forgiveness.

Break through your speed barrier.
In order to provide golfers with all the distance, accuracy and versatility they could ever want from a hybrid, Callaway engineers incorporated advanced Fusion Technology in our most forgiving hybrid design ever.

Fusion Technology
Fusion Technology uses multi-metals, combining a stainless steel body and sole with Metal Injection Molded (MIM), high-density weights to maximize perimeter weighting for a higher moment of inertia (MOI) with an optimized center of gravity (CG). The result is high, strong trajectories that fly farther and land softer.
