Engineered for road riders, the Nucleon PLASMA Back Protector With Straps is Alpinestars’ lightweight motorcycle back protector. Extremely lightweight, it features Alpinestars’ Nucleon PLASMA technology: a viscoelastic, impact-absorbing material designed to deliver high levels of adaptability, breathability, and ventilation. Backed with a soft-touch textile coating, this ultra-adaptive back protector delivers the optimum balance of force dispersion, flexibility, and comfort.

Featuring an embedded Nucleon PLASMA long back protector with a composite semi-rigid thermoplastic central spinal zone on the outer back for additional protection, the protector’s ultra-adaptive geometry compresses and extends to fit, improving coverage, airflow, and all-day comfort. Adjustable, removable straps provide stability and a precise fit when worn under Alpinestars motorcycle jackets and suits.

Composite protection architecture: central semi-rigid thermoplastic spinal zone on the Nucleon PLASMA long back protector enhances impact force dispersion in a critical area.
PLASMA M ventilation design: maximizes airflow and heat dissipation; the pattern continues across the semi-rigid zone to keep ventilation unobstructed.
Anti-tear backing layer: maintains structural integrity by resisting ripping during repeated movement and use.
Adjustable shoulder and waist straps: deliver a precise, personalized fit over different jackets and suits.
Removable shoulder straps: enable quick conversion to a race-specific configuration when required.

CE Level 2-certified Nucleon PLASMA Back Protector with Strap provides effective impact force dispersion, with impact performance significantly exceeding the minimum CE certification requirements.
