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.

It is contructed using four braided fibres of superlight S-glass fiber wrapped in an aluminum alloy sheath.
The fibres are aligned at 0, 90, 22 and-22û orientations which enables stresses to be supported in multi-directions whereas standard carbon sheets are only orientated in one direction. This means that one layer of 4D material has the equivalent properties to four layers of standard carbon layed up at orientations. Consequently 4D material is four times more effective than standard carbon. Furthermore, by using one layer, 4D is also softer and less bulky than 4 layers of carbon.
At 5 and 7 o'clock the multi-directional properties of the 4D braided cloth help stabilize the torsional twist at key points of the racquet.
At 3 and 9 o'clock one layer of 4D braided cloth provides the torsional stability previously only achievable with several layers of carbon fibre. As a result of only one layer being used instead of several this softer material also provides superb touch and feel at ball contact.
