Alpinestars Nucleon Plasma Back Protector

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.

Features:

  • Eco-friendly and sustainable impact absorbing material; a blend of bio-based materials and high performance polyurethane delivers superb adaptability for an enhanced performance fit
  • Highly ventilated for superior airflow and breathability, with a soft-touch inner liner on the skin side for optimum rider 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

Guter Rückenprotektor

Der Protektor in Größe L passt sehr gut zu der Jacke in Größe L. Nichts rutscht oder drückt und durch das flexible Material passt er sich gut dem Rücken an. Bin sehr zufrieden damit.

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!
