4D Braided™: 4D stands for 4 directional braiding. It is constructed using four braided fibers of superight S-glass fiber wrapped in an aluminum alloy sheath. The fibers are aligned at 0, 90, 22 and -22 degree orientations which enables stresses to be supported in multi directions whereas standard carbon sheets are only oriented in one direction. This means that one layer of 4D material has the equivalent properties to four layers of standard carbon layed up at four different 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 providing enhanced stability and increased control.

At 3 and 9 o'clock one layer of 4D braided cloth provides the torsional stability previously only achievable with several layers of carbon fiber. As a result of only one layer being used instead of several, this softer material also provides superb touch and feel at ball contact.

Aerogel Technology: The world's lightest solid and has a strength of up to 4,000 its own weight. The three-dimensional nanometer-sized molecular network delivers an unmatched strength to weight ratio for enhanced stiffness and increased power.
