The HEAD YouTek IG Challenge MP Prestrung Tennis Racquet, with Innegra technology, which utilizes a special melt-spun fiber integrated into the graphite matrix. The fiber was initially developed for the surfboard industry as a way to strengthen the board, providing high durability without significantly increasing the weight. When placed into a racquet, a beneficial side effect was noticed as the fiber possessed a unique flex characteristic that resulted in lower vibration and greater comfort.
Racquet comes pre-strung and with a cover.
