Our revolutionary SmartFlex technology provides protective pads with hinge-like flexibility, allowing uninhibited freedom of motion and is ideal for any sport where players demand complete freedom of movement to maintain accuracy and performance. SmartFlex is comfortable to touch and hardens on impact, providing outstanding protection. After the moment of impact, the pads return to their original, comfortable state. SmartFlex Stretch is an extension of our SmartFlex technology platform. The SmartFlex Stretch pads feature an auxetic design that provides 4-way flexibility which increases mobility and breathability while delivering incredible comfort at the joint. In addition, our pads are waterproof to seal out water and foam-eroding perspiration — and they're machine washable
