Joola Air Rubber is best when used in a maximum thickness, due to the fact that it is 10% lighter than conventional attacking rubbers.
The sponge is very soft (only 40 degrees) but the technologically advanced sponge still allows the ball to catapult outwards quickly unlike other soft-sponge rubbers.
The secret to this advanced sponge is the new ROSnet technology. ROSnet allows the ball to bury itself into the rubber for a longer dwell time due to the structure of the molecules.
