With O3 Ozone Prince has reengineered the O3 Hitting Zone for a more consistent Sweetspot by using CARBON WEAVE MATRIX (CWM). The CWM is positioned around the frame where the O-Ports are. CWM both strengthens and adds stability to the Sweetspot and hitting zone of the racket. The "WAVE" graphic in the inner of the frame is a graphic description of CWM.
