The Alpinestars A-5 Plasma Chest Protector delivers high-performance impact protection and superior ventilation for off-road riders. At its core is the innovative Nucleon Plasma technology—a viscoelastic material engineered from bio-based polymers. This structure remains pliable in all directions to follow the body’s natural contours while maintaining an exceptional ability to dissipate and absorb impact energies.
Designed for maximum breathability, the chest and back protectors are mounted on a highly perforated 3D mesh chassis. This construction ensures constant airflow and provides an additional layer of protection against tire roost. The back protector features a specialized composite construction with a central semi-rigid thermoplastic zone, specifically designed for greater impact force dispersion in critical areas.
Engineered for an optimized performance fit, this protector includes several adjustable features to ensure comfort in all riding positions:
-
Adaptive Fit: Independent side wings and a semi-rigid outer shell allow the protector to move with the rider for total freedom of movement.
-
Customizable Comfort: Equipped with adjustable shoulder and side straps, along with removable soft tactile, thermoformed shoulder padding.
-
Advanced Cooling: The Nucleon Plasma protectors are ribbed to reduce skin contact and enhance airflow.
-
Integrated Protection: Liners on the chest and back protectors maintain structural integrity and reduce the risk of material tearing.
-
BNS Compatibility: Features dedicated shoulder pull tabs for seamless integration with Alpinestars Bionic Neck Supports.
Lightweight and highly ventilated, this protective gear offers extensive coverage without compromising on agility, making it an essential choice for riders demanding both safety and performance.
