Swirl Geometry is a unique frame geometry providing a twisted aerodynamic profile. The frame reflexively trace the biomechanics of your stroke, increasing head speed and manoeuvrability. The unique manufacturing process of interlinking and overlapping composite fibres that are woven over the frame creates a high resilient design. This seamless construction evenly dissipates the pressure that a racquet receives during aggressive play protects the underlying structure.
