Is maximum protection and maximum comfort even possible? We say yes! The pre-curved ergonomic Natural Fit form combines maximum flexibility with outstanding breathability while silicone print on the inside prevents unwanted slippage. But the star of the show? That's courtesy of the abrasion-resistant knee zones and ultra-flexible yet super-streamlined protector made from SAS-Tec SC-1/KA visco-elastic soft foam known for its extremely high damping properties. You knees deserve the best!
