Dunlop 4D Technology
Dunlop has further enhanced its Aerogel technology by taking it to the next dimension with 4D braiding.  4D stands for 4 directional braiding. It is constructed using four braided fibres of superight S-glass fiber wrapped in an aluminum alloy sheath.

Four directional braided material is used at key points on the racket frame to significantly increase racket stability.

- at 5 and 7 o'clock to minimize frame torsion and increase control

- at 3 and 9 o'clock for increased stability and enhanced touch and feel

The results are exceptional racket control without sacrificing the Dunlop racket feel. 4D braiding has been implemented across the whole Dunlop Aerogel line, offering outstanding benefits to players of all abilities.

Dunlop AeroGel Technology
AeroGel is the new breed of racquet material - Light and Strong:
AeroGel (like Head MicroGel and Wilson K Factor) is extremely light, strong and rigid.  It has an unmatched strength to weight ratio.

Now a racquet can be designed for great strength and stability without adding undesired weight.  There can be special shaping of the head, yoke, and connector sections that was not possible with older materials.

Try an AeroGel, you will see that balls go exactly where you want, you have great feel, and you also have good comfort and low vibration.
Dunlop M-Fil Technology
M-Fil is a three dimensional braid that is infused into the racquets carbon-fiber frame.  This stabilizes the frame in all dimensions to provide control and stability.
Dunlop VibraCore Technology
Vibracore Technology dramatically reduces frame vibrations. At ball impact, shock waves are absorbed into a silconnerubbercore in the shaft of the racquet and are not allowed to travel down to the handle. This provides exceptional comfort  and significantly reduces the risk of tennis elbow.

Virbacore, like Babolat Cortex, is especially effective in more powerful frames.
