Delivering what players worldwide have requested, Scotty's new Phantom X 5.5 is not only a rolling change to a proven design. It's as close to Justin Thomas' Tour setup as you can possibly get. From prototype to full production, the new Phantom X 5.5 replaces its predecessor and includes the arc-enhancing small slant neck inspired by JT's configuration, as well as the same overall sizing and material makeup. Designed to promote a more flowing "blade-like" feel with the stability benefits of a mallet, the milled sight line on the topline provides alignment, while its clean craftsmanship instills confidence. The solid face/body is precision milled 303 stainless steel integrated with an aluminum sole plate and customizable stainless steel sole weights for pure playability. This combination of heavier steel and lighter aluminum moves weight to the perimeter of the head, increasing MOI, stability and forgiveness. Satisfaction and authenticity are guaranteed. Standard Titleist warranty applies.
