Twenty years of development marks the end of the titanium era. The all new 60X Carbon Twist Face is 44% lighter than an equivalent titanium face, while also being 11% larger than SIM2 and SIM2 Max drivers and nearly 20% larger than the 2020 SIM driver. Sixty layers of carbon fiber have been strategically designed to optimize energy transfer to deliver fast ball speeds over a large area, resulting in optimal distance and forgiveness. The 60X Carbon Twist Face is encased by a polyurethane cover, featuring a revolutionary new nanotexture technology. The nanotexture cover is used to fine tune launch and spin to optimize total distance regardless of playing conditions. The Inertia Generator remains the foundational source of refined aerodynamic properties. The weight savings of the 60x Carbon Twist Face has allowed more weight to be positioned low and deep in the head. Additional weight savings come from the removal of the Sliding Weight Track. Compared to Stealth Plus+, this model offers 15% greater MOI. Historically, draw bias drivers have not been forgiving - as the higher CG needed to create the necessary spin led to a lower MOI. Stealth HD flips this design convention on its head, delivering draw-bias with a stable feel and the highest MOI of any driver in the Stealth family.
