The d3o technology is able to sense the needs of the players during different strokes (it's able to adapt to you). On high-speed impacts (aggressive shots), the smart molecules lock together within nanoseconds and dramatically increase the stiffness of the whole racquet frame to provide maximum power. On slow-speed impacts (slice or drop shots), the d3o molecules absorb the impact to provide a softer touch for better feel. What does this mean to a tennis player? Passing shots are even harder and drop shots more precise, rewarding your spontaneity and supporting your courageous decisions.

This Head Innegra hybrid-composite structure is integrated into the racquet for shock absorption and improved stability. As a result vibrations are reduced by up to 17% on ball impact for improved control and precision -- protecting the player from the forces of a ball impact. On top of this, Head's new hybrid-composite structure with the ultra tough Innegra fiber considerably extends the performance of a Head racquet. With Innegra, racquets remain in perfect condition without losing any performance properties.
