2 ply  Zephylium  synthetic polymer in-woven fibres + 5 natural wood.

Creative synergy of wood and composite material. Zephylium in new construction makes Hayabusa Zi feel natural but sharper than all wood blades. Leveraged spin loading and increased ball energy (commonly noted as ‘heavy ball’) are made by the unique construction inside. Flexible but solid contact with the ball to generate heavy spins identifies Zi as the new European powerblade. New paradigm defines Hayabusa optimizing controversial properties to make the unprecedented table tennis weapon.
