With a new 4D braided technology, Dunlop's venerable 300 offers improved stability from all areas of the court. The 4 directional braiding adds strength and stability at key points of the racquet while maintaining touch and feel. On court we found the racquet to feel incredibly solid -- improving on the feel of the impressive Aerogel and M-FiL versions. The Aerogel 4D 300 offers easy maneuverability and superb ball feel. Our TW playtesters found easy access to quick swing speeds off the baseline with excellent access to spin and plenty of pop on tap. At net, the racquet provides a quick feel, with touch being a standout quality. Like its predecessors, the Aerogel 300 4D offers a generous sweetspot from its 98sq. inch headsize. Players rated 4.0+ NTRP who are looking for an arm-friendly option that offers controllable spin and power should check out the Aerogel 4D 300.
