Developed for off-road youth, the Bionic Plasma Youth Knee Protector is an MX knee protector built for motocross and trail protection. It features a CE Level 1 EN 1621‑1:2012 Nucleon PLASMA insert in USDA Certified Biobased viscoelastic material, plus a lightweight, ventilated 3D mesh chassis and abrasion-resistant knee panel. Open-back airflow, stretch rear mesh, and silicone upper hems support hot-weather cooling, fit, and stability for all‑day comfort.

  • Nucleon PLASMA Technology: viscoelastic impact absorber disperses energy while maintaining full-knee coverage across aggressive riding positions.
  • Ergonomic Articulation: multi-directional flexibility mirrors natural knee motion for non-restrictive movement and precise bike control.
  • Ventilated Chassis: 3D mesh front panel teams with abrasion-resistant outer fabric for high airflow and long-lasting durability in off-road conditions.
  • Heat Management: open-back, open-knee architecture with stretch mesh behind the calf maximizes breathability for all-day comfort.
  • Lateral Coverage Design: wraparound knee profile shields critical side zones for added confidence on rough terrain.
  • USDA Certified Biobased viscoelastic impact-absorbing material engineered for effective energy management.
  • Extra side padding for extended lateral coverage of the knee.
  • CE Level 1-certified Nucleon PLASMA knee protector for tested impact attenuation.
  • Soft inner padding provides supplementary cushioning in key contact areas.
  • Pre-shaped construction maintains consistent coverage through knee articulation.
  • Anatomically sculpted upper calf and upper hem with silicone strips keep the protector securely positioned for precise impact coverage.
  • Nucleon PLASMA knee protector insert molded from USDA Certified Biobased viscoelastic polymer compound for impact energy management
  • Integrated lateral padding panels bonded to the chassis side zones for extended coverage
  • EN 1621-1:2012 Level 1 Nucleon PLASMA knee insert is removable via an internal pocket for serviceability
  • Layered soft tactile inner padding on the skin-side panels for a smooth interface
  • Pre-shaped chassis with soft-touch, perforated stretch padding, a ventilated 3D mesh front panel, abrasion-resistant textile reinforcement over the knee, and an open-back design with stretch mesh at the rear
  • Anatomically sculpted upper calf patterning with silicone gripper strips at the upper hem to stabilize the chassis on the leg
  • Approximate weight by size: S/M 350 g; L/XL 400 g; XXL 450 g
