Babolat's Cortex shaft vibration dampening system is designed to offer greater comfort during play. Available in two versions, the Cortex system used in the Pure series of racquets reduces harmful racquet vibrations without filtering out the feedback required for feel. The result of filtering unnecessary vibrations results in what Babolat calls a "pure feel." The Cortex system used in other Babolat racquets filters and dampens for maximum comfort.
