SX-1 Plasma Knee Guards - Black/Red/Cool Gray - L/XL
The Alpinestars SX-1 Plasma Knee Guards provide superior impact protection combined with innovative design features for optimal riding comfort and safety. Built with a plasma knee protector embedded into a highly ventilated semi-rigid frame, these guards are engineered to dissipate impact energy effectively while maintaining flexibility. The use of a USDA biobased viscoelastic material ensures pliability in all directions, allowing for natural movement and excellent shock absorption during aggressive riding sessions. The dual density co-injected frame offers a supportive structure that adapts to various leg sizes, enhancing both stability and comfort. A scooped lower extension made from a soft polymeric blend prevents pressure points caused by the boot pressing against the protector, and the upper extension design prevents skin irritation, ensuring a comfortable fit throughout your ride.
