Head have developed the new Innegra hybrid-composite structure to improve stability, shock absorption and extend the performance of your racquet. Innegra is the world's lightest high performance fibre. Combining Innegra with Head's carbon technology leads to a new ultra tough hybrid composite.

The YouTek series of racquets combines superior technologies to perfectly match your individual needs. Whether your game is aggressive and adventurous or consistent and smooth Head believes that the YouTek range will enhance your performance and bring out the best in you.

d3o is a futuristic new material which belongs to the "smart materials" category. Head have placed this new material in the shaft of the racquet. This material can change its behaviour under different conditions. This translates on the tennis court with the d3o  allowing the racquet to adapt to the needs of you - the player. On your high impact (or aggressive) shots the smart molecules will lock together within nanoseconds and dramatically increase the stiffness of the whole racquet frame and therefore providing maximum power. On your slower speed impact shots like a slice or drop shot the d3o molecules will absorb the impact therefore providing a softer touch for better feel. This means passing shots will be even harder and drop shots will be more precise!
