Alpinestars A-5 Plasma Chest Protector 6700825-132

The Alpinestars A-5 Plasma Chest Protector is engineered to deliver superior impact protection and comfort during rigorous motocross and off-road riding. Constructed with a highly perforated 3D mesh chassis, it offers exceptional airflow and breathability, helping riders stay cool and dry in demanding conditions. The design features independent side wings from the main semi-rigid outer shell, allowing for a fully adaptive fit that follows the body's contours for enhanced comfort and unrestricted movement in any riding position.

At the heart of this protection system is the Nucleon Plasma material—a viscoelastic, bio-based polymer engineered to be pliable in all directions while maintaining the ability to dissipate high-energy impacts. The back protector utilizes a composite construction with a central semi-rigid thermoplastic zone for greater impact force dispersion in critical areas. Lightweight and ventilated, the A-5 Plasma ensures maximum coverage without the bulk, while the ribbed design of the protectors further enhances airflow and reduces skin contact for long-ride comfort.

For a personalized performance fit, the protector is equipped with adjustable shoulder and side straps. Soft, thermoformed shoulder padding provides extra tactile comfort and can be removed based on rider preference. Integrated liners maintain the structural integrity of the Nucleon Plasma components, reducing the risk of tearing and ensuring long-term durability. Additionally, the 3D mesh chassis provides added protection against tire roost, while dedicated shoulder pull tabs ensure seamless compatibility with Bionic Neck Support (BNS) systems.
