The Dunlop Aerogel 4D 300 Tour is the ultimate choice for the advanced player who wants maximum control. Featuring Dunlop's new 4D BRAIDED technology that offers 33% more stability and control. 4D is constructed using four braided fibers of super light S glass fiber wrapped in an aluminum alloy sheath and placed at 4 different touchpoints around the frame. Because 4D requires only 1 layer of carbon fiber instead of the conventional 4 layers, the racquet is then softer, enhancing touch and feel at ball contact. The Aerogel 4D 300 Tour differs from the standard 4D 300 because it features an 18 x 20 dense string pattern for control and precision and a heftier weight. This racquet is better suited to players who have long, fast swings. The flexible frame and head light balance offer high maneuverability needed in today's fast pace, aggressive game. Recommended for 4.5 7.0 level players.
