Alpinestars A-4 Plasma Chest Protector

Alpinestars A-4 Plasma Chest Protector

Engineered for the rigors of off-road endeavors, the A-4 Plasma Chest Protector stands out with its semi-rigid thermoplastic polyhedron front shield coupled with a Nucleon Plasma back protector. It emphasizes real-world application with a design that's lightweight, breathable, and conforms to the rider's body while ensuring exceptional defense against impacts. The front chest shield benefits from a geodesic polyhedron pattern that minimizes material usage while maintaining structural integrity, achieving superior strength with less material compared to flat surfaces. This ingenuity not only reduces weight but also enhances ventilation, yielding a chest protector whose parts synergize to exceed expectations. On the flip side, the Nucleon Plasma Back Protector is sculpted from a USDA Certified Biobased viscoelastic compound. It boasts adaptable flexibility, hugging the rider snugly and dissipating forces effectively during impacts. It guarantees extensive protection and cooling properties, fostering a safer and more focused off-road experience.
