The Yonex Aero-Box Vari Frame combines the aerodynamic profile of a frame head that is pared on the sides for a quicker swingthrough in any situation, with a squared upper and lower frame section and additional Tungsten IPS weighting for 15% more weight and face stability than any ordinary racquet.

The Aero-Box Vari Frame reduces wind drag by 10% compared with a standard air-flow pattern, maximizing the power of the swing and the transfer of energy to the ball. In addition, besides high anti-torque performance for extra power with control the Aero-Box Vari Frame's extended dwell time makes it easier to create high-speed tactical shots that sizzle with spin.
