Alpinestars SX-1 Plasma Knee Protector Black Red Cool Gray - Technical hinged knee protector for maximum protection and comfort

High-end protection, total freedom of movement: the SX-1 Plasma is the perfect combination of innovation and comfort.

Developed for demanding motocross, enduro and off-road riders, the SX-1 Plasma Knee Protector Black Red Cool Gray offers an ideal combination of advanced protection, lasting comfort and natural mobility.
Designed with a ventilated semi-rigid frame and incorporating the Nucleon Plasma protector, this kneepad effectively absorbs shocks while perfectly following the knee's movements.

Its core technology, the Dual Gear System (DGS), reproduces the natural kinematics of the knee joint thanks to a fluid double-pivot system. The result: total freedom of movement without discomfort, even in the most dynamic phases.
The dual-density co-injected frame is lightweight and durable, avoiding the pressure points often caused by boots while ensuring a firm, snug fit.
The rigid kneecap fully protects the knee against frontal or lateral impacts, while the double Velcro straps guarantee a fast, secure fit.

Simply put, the SX-1 Plasma gives you the perfect balance of flexibility, safety and comfort to ride longer, freer and with confidence.
