The Prince Ozone Tour is the latest update to the Prince O3 Tour and is the first true players offering in the Prince Ozone racquet line (being used in 2008 by Davydenko.) Thanks to the use of O-Ports around the perimeter of the frame, the Ozone Tour has a livelier response than typical players racquets across the entire string bed. Prince enhances the sweetspot with Carbon Wave Matrix Construction, in which Prince layers the graphite fibers in a wave pattern. This wave pattern complements the angular orientation of the other graphite layers, offering superior power versus traditional graphite construction techniques.
