SX-1 Plasma Knee Protector
Expertly designed for off-road performance, the SX-1 PLASMA Knee Protector features a highly ventilated semi-rigid frame integrated with Nucleon PLASMA viscoelastic protection. The Dual Gear System (DGS) ensures smooth hinge function to support natural knee articulation while dissipating impact energy. This CE Level 1 certified protector delivers a secure, adaptive fit with a dual strap closure system for maximum comfort and stability.
  • Nucleon PLASMA Protection: USDA Certified Biobased viscoelastic material offers multi-directional pliability and a custom fit, effectively dissipating impact energy.
  • Dual Density Co-Injected Frame: Engineered with scooped upper and lower extensions to eliminate pressure points and prevent the protector from digging into the skin.
  • Dual Gear System (DGS): Integrated gear profiles in the upper and lower frames ensure smooth hinge function and promote natural knee articulation.
  • Ergonomic Adaptive Fit: Sculpted frames feature strategically positioned rigid and flexible over-injected shells to accommodate a wide range of leg sizes securely.
  • Patella System Protection: Engineered to provide full coverage of the knee cup at all degrees of extension, with a rigid outer shell to prevent injuries from handlebar strikes.
  • Lightweight knee protection with extensive protective coverage.
  • Upper and lower frames are constructed from high-performance polymer for optimized flexibility and strength.
  • Integrated dual pivot hinge system follows natural knee movement and maintains protector positioning while riding.
  • Slim ergonomic frame design for a low-profile fit.
  • Dual strap closure system with hook-and-loop and snap-fit buckles for a personalized, secure fit.
