Key Features

Construction

Bio-based viscoelastic compound
The Nucleon PLASMA Back Protector is constructed from a bio-based viscoelastic impact-absorbing compound containing at least 25% bio-based content, 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 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.

How does Nucleon Plasma Technology differ from traditional back protectors?

Nucleon Plasma is an eco-friendly, sustainable impact-absorbing material unique to Alpinestars. It delivers class-leading adaptability and breathability while remaining extremely lightweight. The material's cellular structure provides excellent force dispersion without sacrificing flexibility or comfort during riding.

Can I wash the Nucleon Plasma Full Back Protector Insert?
