Product details

ALPINESTARS 2026 BIONIC PLASMA KNEE PROTECTOR – YOUTH

Engineered specifically for younger off-road riders, the Bionic PLASMA Youth Knee Protector is lightweight, comfortable, and protective, featuring a removable Nucleon PLASMA knee protector embedded in a highly breathable chassis for enhanced rider comfort.

key features

  • Highly Comfortable: The Nucleon PLASMA knee protector is made from a USDA Certified Biobased viscoelastic material that absorbs and disperses impact energy while providing maximum coverage in all riding positions. Engineered for multi-directional pliability, the protector conforms to the knee for a snug and secure fit, and delivers reliable protection.
  • Ventilated Chassis Design: The chassis features a 3D mesh front panel for superior levels of ventilation and airflow, along with abrasion-resistant fabric that covers the knee area.
  • Stretch Mesh, Ventilated Construction: Soft, stretch mesh at the rear of the lower legs provides a comfortable fit for riders with various calf sizes, while the open knee construction behind the knee helps to prevent heat build-up while maximizes ventilation.
  • Extended Coverage: Extra side padding for extended coverage.
