STIGA MANTRA H. The NEW STIGA Mantra is developed with the latest Japanese rubber technology and offers the perfect balance of synthetic and natural rubber. This new rubber mixture creates a tension between the surface and the sponge resulting in an incredible catapult effect. Microscopic air bubbles in the sponge (Oxygen Capsule System) provide great speed with a stable and consistent hit and touch. The Mantra H has a hard sponge which creates the classic power feel with extreme attacking possibilities. It delivers very high speed and effectiveness from a short distance and allows excellent blocking abilities in close over the table action. The optimized top sheet allows heavy rotation topspin in flicks and offensive returns. This rubber is perfect for powerful offensive players who require the highest in rubber quality and performance.
