Alpinestars Bionic Pro Plasma Knee Protectors: Serious knee protection engineered to move naturally with your body, not against it.

Features

• Removable Nucleon Plasma protector: flexible until impact, firm when it matters
• Dual thermoplastic shells over the patella: extra abrasion resistance where you need it most
• Breathable inner lining: comfortable enough for long rides
• 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
• Two independent thermoplastic shells are strategically positioned over the patella for enhanced levels of abrasion resistance and sliding performance, while also delivering additional impact performance
• The slip joint construction ensures high levels of articulation while simultaneously ensuring the protector remains snugly in position
• The wide elasticated top strap delivers superior comfort and a secure closure
• Nucleon Plasma is a viscoelastic material engineered from bio-based polymers and formed into a structure that is pliable in all directions while maintaining the ability to dissipate impact energies
