Innegra is today the world's lightest fiber. Its extreme solidity combined with HEAD Advanced Carbon technology has enabled the creation of a new high performance structure. This new composite structure HEAD Innegra is integrated in the frame to reduce vibrations on impact and increase stability. the vibrations, in fact, are reduced 17% in order to assure maximum control and precision. Additionally, the frame maintains its original structure for a longer period of time, wihtout losing any if its characteristics, increasing, in a big way, the performance of the racquet.
