Frequently asked questions Hide FAQs
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.
