Description

Ergonomically designed for all forms of road riding, the Nucleon PLASMA Back Protector with Strap has been engineered to be lightweight, breathable, comfortable and protective.

Details:

  • The Level 2 CE certified back protector is a composite construction and has a central semi-rigid thermoplastic zone on a Nucleon PLASMA long back protector for greater impact force dispersion in a critical area.
  • The innovative PLASMA M design delivers maximum airflow and heat dissipation and this M design is replicated on the strategically aligned semi-rigid zone for guaranteed unobstructed ventilation.
  • The soft tactile backing guarantees structural integrity of the protector by preventing any potential tearing.
  • Fully adjustable shoulder and fully adjustable waist straps for a truly customisable fit.
  • The shoulder straps are removable allowing the protector to be easily and quickly converted into a race-specific version.
  • PLASMA is constructed from USDA certified bio-based eco-friendly and sustainable impact absorbing material.
  • Ultra-comfortable soft and flexible Nucleon PLASMA viscoelastic compound delivers enhanced rider comfort.
  • Highly breathable due to the engineered structure and the channelled inner surface that allows air circulation.
  • Constructed with a soft tactile inner liner for additional rider comfort.
  • The super lightweight back protector is developed in three waist-to-shoulder dimensions to cover all body sizes.
  • The adjustable side straps are equipped with a V-configuration to ensure the back protector has a performance fit that follows the curvature of the spine.
  • EN 1621-2:2014 Level 2
