The Redstone is a diamond-shaped racket of extreme power and stiffness, thanks to the use of a double layer of 18K carbon fiber, making it the stiffest racket in the entire Hirostar collection. Designed for advanced and professional players who want to unleash the full power of their arm in their shots. Despite its shape and aggressive design, its convex bridge absorbs most of the vibrations without putting excessive strain on the elbow or shoulder. The glossy finish with embossed 3D Hirostar logos gives it a textured feel.
