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.
