Alpinestars Nucleon Plasma Full Chest Protector Hook and Loop

The Alpinestars Nucleon Plasma Full Chest Protector is a lightweight, low-profile motorcycle chest protector insert engineered to provide CE Level 2 impact protection without sacrificing ventilation or riding comfort. Designed for compatible Alpinestars motorcycle jackets and hoodies, it uses a large hook-and-loop attachment area for secure and convenient integration.

Built around Alpinestars' advanced Nucleon PLASMA viscoelastic material, the protector adapts comfortably to the rider's body while providing effective impact energy absorption. A semi-rigid thermoplastic central zone improves impact force dispersion, while the highly ventilated PLASMA M structure keeps airflow moving through the protector.
