Compress high intensity which enhance resilience and stability. Reduce air resistance, which enable the player with a smoother shot. Nano Fortify is composed by numerous tube-shaped carbon fiber. When applying this technology to the shaft, Nano Fortify can optimize high resilience.  With bending strength to generate high repulsion, which enhance  attacking power on every single hit.   Innovative technology combining the two popular frame structure SWORD and AERODYNAMIC, the AERO-SWORD can efficiently reduce air resistance and allowing a faster and greater hitback.
