Alpinestars A-5 Plasma Chest Protector - Black/Red/White

Designed for all off-road disciplines, from motocross to supercross, the A-5 PLASMA chest protector offers complete and ergonomic protection. Composed of Nucleon PLASMA protectors and semi-rigid thermoplastic chest and back protectors, it combines lightness, breathability, comfort, and resistance for maximum performance on all terrains.

The CE-certified Level 2 chest and back protectors are mounted on a highly perforated 3D mesh for superior airflow and breathability.

The side wings are independent of the main semi-rigid outer shell of the chest protector to ensure a fully adaptive fit.

The CE-certified Level 2 back protector is a composite structure and features a central semi-rigid thermoplastic zone on a Nucleon PLASMA back protector for greater dispersion of impact force in a critical area.

The protectors feature an adaptive fit system that perfectly follows the contours of the body for maximum freedom of movement and optimal comfort.

Nucleon PLASMA is a viscoelastic material made from bio-based polymers and molded to form a flexible structure in all directions, while maintaining the ability to dissipate impact energy. Lightweight and perfectly ventilated, this knee protector offers strong dispersion and absorption of impact force while ensuring maximum coverage regardless of the riding position.
