What level of protection does the Nucleon Plasma Full Back Protector Insert provide?

This back protector is CE Level 2 and UKCA certified, delivering the highest standard of impact protection for motorcycle riding. Level 2 certification ensures superior energy absorption during impacts compared to Level 1 protectors.

Is the Nucleon Plasma Full Back Protector Insert compatible with Alpinestars jackets?

Yes, this insert is designed to fit Alpinestars jackets with compatible back protector pockets. Its ultra-adaptive design and flexible construction allow it to conform to different jacket models while maintaining optimal protection positioning.

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?

The protector features a soft-touch textile backing that can be spot cleaned. Remove the insert from your jacket before cleaning. Avoid machine washing or submerging the protector, as this may affect the Plasma material's protective properties. Allow to air dry completely before reinstalling.

The extremely lightweight Level 2 CE and UKCA certified Nucleon Plasma Full 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.

Ventilation system: Extensive perforations plus lateral and longitudinal airflow channels promote continuous cooling and breathability; soft-touch inner liner enhances on-skin comfort.
Lightweight construction: Low-mass back protector insert offered in three waist-to-shoulder dimensions for precise coverage across a wide range of body sizes.
Nucleon Plasma Technology: Race-developed material and design balance force dispersion, density, thickness, and pliability for confident, all-ride comfort.
Tailored geometry: Zoned lattice mapping allows high airflow and flexibility while maintaining coverage and stability inside the jacket pocket.
Adaptive flexibility: Innovative structure compresses and extends to move with the rider, delivering an ultra-adaptive, low-bulk fit.

Breathability

The innovative structural design allows the protector to be slim and to have a high level of breathability, as well as flexibility, due to the high percentage of perforation attributed to the "M" shaped design.

Comfort

The inner side of certain protectors are laminated with a smooth fabric which provides a soft and comfortable feeling. The fabric adds durability and prevents possible tearing of the viscoelastic material.

Adaptive

The compound, combined with the 3D engineered structure, provides a very flexible and adaptive platform. The "M-shaped" structural design maximizes the area of protection while at the same time provides superior adaptivity.

Impact Performance

The combination of this structure and material results in a protector that is equally protective at any given point of the structure, while at the same time, is also flexible in any direction.
