Stiga Airoc Series
The Stiga Airoc rubbers were introduced before the Mantra series and after the Stiga Calibra series. These rubbers were specifically designed for the older celluloid ball but are still regarded as fast by modern standards. Like the Mantra series, the Airoc rubbers are made in Japan and are better suited for smashing and driving, with less emphasis on generating spin. The different variants are distinguished by their sponge hardness.
