Features:
AERO Frame - Smoother contours throughout the racquet head for less wind resistance and extra racquet speed.
 
ISOMETRIC Enlarged Sweet Spot -  Compared to a conventional round frame, a square-shaped ISOMETRICTM racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings.
 
Sonic Flare System - Max Acceleration - The revolutionary new graphite material TORAYCAR M40X and SUPER HMG provide unrivalled power and stability for maximum shuttle acceleration.
 
Super Slim Shaft - Reduced Air Resistance - The slimmest racquet ever produced by YONEX vastly reduces air resistance whilst providing maximum feel.
