Alpinestars RK-7 Plasma Knee Braces — Size S, Black

The slim, ergonomic knee brace delivers high off-road performance and comfort during dynamic movement while remaining lightweight, breathable and protective.

It features a free-floating Nucleon Plasma knee protector encased in an asymmetric fiber-reinforced frame for superior rigidity and effective impact dispersion.

• Replaceable knee cups with a polyurethane outer shell backed by Nucleon Plasma for optimal impact absorption, flexibility and scratch resistance.
• Strategically positioned, replaceable upper and lower patella extensions provide maximum coverage through all flexion and extension angles.
• An extremely stable, slim-design four-point hinge system follows natural articulation while exchangeable extension stops (0°–30°) set the desired opening angle.
• Stainless-steel hinge bushings receive an anti-oxidation treatment for enhanced durability.
• Soft-touch thermoformed padding and profiled X-straps with non-slip backing ensure a secure, comfortable fit without pinching behind the knee.
• High-tensile buckles with a keyhole snapping system enable robust but easy strapping and locking.
• Nucleon Plasma is a bio-based, viscoelastic material engineered to dissipate impact energy while remaining pliable in all directions.
• Knee protector certified to EN 1621-1:2012 Level 1.

Construction materials include polyamide, thermoplastic polyurethane, polyethylene, polyurethane, steel, neoprene and polyester for a balance of strength, comfort and ventilation.
