Alpinestars SX-1 Plasma Knee Guards

Why riders pick it

• Features a Plasma Knee Protector embedded into a highly ventilated semi-rigid frame construction for superior impact protection, while the integrated Dual Gear System (DGS) promotes the natural articulation of the knee
• Constructed from a USDA Biobased viscoelastic material, which is molded into a structure that is pliable in all directions while maintaining the ability to dissipate impact energy
• The same scooped design is also applied to the upper extension, and this prevents the protector digging into the skin and causing discomfort while riding
• Controlled Natural Movement, Dual Gear System (DGS), both the upper and lower frames have integrated gear profiles that ensure a smooth hinge function to promote the natural articulation of the knee
• Features strategically positioned over-injected rigid and flexible shells to ensure the frames adapt to a wide variety of leg circumferences
• The Patella System is engineered to offer full coverage of the knee cup regardless of the degree of extension while the rigid outer Patella System shell prevents injuries from handlebar strikes
