The YouTek Prestige Mid features d30 technology. Weighing 350 grams and with a head size of 93 square inches this will suit the more advanced player.

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!

The YouTek racquets also feature Head's Teflon grommet system which reduces friction. This holds back the movement of the string by creating a self-lubricating effect in the base material, allowing the strings to slide throught the grommets with nearly no friction. This means the energy loss is minimal.

 *Please note these racquets do not come with covers.
