The extremely lightweight Level 2 Nucleon Plasma Back Protector Insert features Alpinestars’ Nucleon Plasma Technology. Unique to Alpinestars, Plasma is an eco-friendly, sustainable and lightweight impact absorbing material, while its clever design delivers class-leading levels of adaptability, breathability and ventilation. Backed with a soft-touch textile coating, this ultra-adaptive protector delivers the optimum balance of force dispersion, flexibility and comfort.

  • The super lightweight back protector insert is developed in three waist-to-shoulder dimensions in order to cover all body sizes
  • 60 years of innovation and extensive testing and research have resulted in Plasma Technology; the perfect balance between impact force absorption, density, thickness and pliability
  • The adoption of Nucleon Plasma Technology allows Alpinestars to tailor the geometry throughout the protector, resulting in extensive perforations while still far exceeding the impact performance; Another standout feature of this design is the extensive number of lateral and longitudinal ventilation channels for effective heat dissipation

Highly Recommended Product For Your Alpinestars Jacket!

Really happy with my purchase of this back protector. It was super simple to install into my Alpinestars Atem 4 leather jacket and didn't make the jacket feel bulky to wear. The back protector foam just moulds to your body's contour - I don't really even feel it on my back when riding. Knowing that I have this product installed, gives me added peace of mind. Highly recommend!

Some flexiblity and breathability too!

This protector's design is top notch. Definitely inspires confidence when in a quality jacket. For protection, it is best to pay slightly more than the alternative products and get the good stuff. The price was right at FC-Moto!

CE Level 2 back protector

CE level 2 protector. Soft when worn and hard when needed. Shape mould to body after warmup when wearing the jacket and don’t feel it is there.
