TNT2® processing enhances playability, multiwrap construction with textured surface offers enhanced feel, power and control.
Multiwrap Elastalon™ center core and outer wraps.
TNT2 Technology enhances GAMMA synthetic strings offering the greatest combination of power, control and shock reduction of any premium tennis string including natural gut.
This second generation Thermo Nuclear Process greatly improves two key factors that relate to a string’s performance: dynamic elasticity (storing energy) and dynamic resiliency (returning energy to the ball). When these two important factors are enhanced the ball will not only stay on the strings longer for maximum control and accuracy, but also return more energy to the ball for increased speed and power.
