d3o™: The frame-inlay d3o™ is a smart material. The specially designed molecules in d3o™ react on different impacts within nano seconds. They stay soft during slow hits and lock together on hard strokes. With this behavior, d3o™ is able to sense the needs of your play and adapts to you. It provides maximum power as well as softer touch for a better feel.

Innegra™: Innegra™ is the world's lightest high performance fiber in the industry today. HEAD's advanced carbon composite technology combined with Innegra™ forms an extremely tough fiber. The new high composite structure is integrated into the racquet for shock absorption and improved stability. Vibration at ball impact is reduced by up to 17% for unmatched control and precision and is easier on your arm. HEAD's new hybrid-composite structure considerably extends the performance of your HEAD racquet at the highest level, giving you consistent performance over the entire life of your frame.
