The Alpinestars Nucleon Plasma Full Back Insert delivers premium impact protection engineered for serious riders. Built with Alpinestars’ proprietary Nucleon Plasma Technology, this back protector uses a bio-based, high-performance polyurethane compound that is lightweight, eco-friendly, and purpose-built for force dispersion.
The insert conforms dynamically to the rider’s spine, compressing and extending with body movement for an adaptive, secure fit. Multiple lateral and longitudinal ventilation channels promote consistent airflow, reducing heat buildup during extended rides. A soft-touch textile interior lining minimizes skin irritation and maximizes all-day comfort.
