Alpinestars Bionic Pro Plasma Knee Protector - Black/Red/White

Anatomically profiled for all forms of off-road riding, the Bionic Pro PLASMA Knee Protector has been engineered to be lightweight, breathable, comfortable and protective, and features a removable Nucleon PLASMA knee protector embedded into a chassis that is abrasion resistant on the outer and highly breathable on the inner for maximum performance. Features: Motocross Knee Protectors Patella coverage and slide zones: dual‑zone protection over the kneecap promotes controlled sliding to reduce snagging and surface wear while enhancing abrasion defense in off‑road conditions. Multi‑axis flex pattern: an engineered hinge path follows natural knee movement for unrestricted transitions between seated and standing riding. Fit system: a wide, elasticated top strap spreads pressure for day‑long comfort and a quick, secure closure over socks or base layers. Energy management core: low‑bulk viscoelastic structure disperses impact loads across a wide area to maintain full‑knee coverage through deep flex and long motos.
