Key Features

Construction

Bio-based PLASMA compound
The Nucleon PLASMA Back Protector is constructed from a bio-based viscoelastic impact-absorbing compound containing no less than 25% bio-based content and molded into a precision-engineered geometry. The PLASMA material dissipates impact energy and significantly reduces transmitted forces through controlled material response.

Low-profile PLASMA geometry
The low-profile PLASMA geometry is specifically developed to compress and extend with movement while supporting airflow through its channeled and highly perforated design.

Waist-to-shoulder lengths
The lightweight back protector insert is available in three waist-to-shoulder lengths to fit a wide range of body sizes.

Frequently asked questions Hide FAQs
What certification level does the Nucleon Plasma Back Protector Insert have?

The Nucleon Plasma Back Protector Insert is CE Level 2 and UKCA certified, providing high-impact protection for motorcycle riding. Level 2 certification indicates superior energy absorption compared to Level 1 protectors, making it suitable for both street and sport riding applications.

Is the Nucleon Plasma Back Protector compatible with all Alpinestars jackets?

This insert is designed to fit Alpinestars jackets and suits with back protector pockets. It features an ultra-adaptive design that conforms to different pocket sizes and body shapes. Check your specific jacket's compatibility to ensure it includes a dedicated back protector pocket.

How does Nucleon Plasma Technology differ from traditional foam protectors?

Nucleon Plasma is a lightweight, eco-friendly impact-absorbing material unique to Alpinestars that offers superior breathability and ventilation compared to traditional foam. Its molecular structure provides class-leading adaptability and flexibility while maintaining Level 2 CE protection, resulting in better comfort during extended riding sessions without compromising safety performance.

Can the Nucleon Plasma Back Protector be washed?

The protector features a soft-touch textile backing that can be spot-cleaned with mild soap and water. Allow it to air dry completely before reinserting it into your jacket. Avoid machine washing, tumble drying, or exposing it to direct heat sources, as these may compromise the protective properties of the Plasma material.
