A-4 Plasma Roost Guard - Black/Red/White - M/L
Designed specifically for all forms of off-road riding, the Alpinestars A-4 Plasma Roost Guard offers optimal protection combined with superior comfort. The semi-rigid thermoplastic polyhedron chest protector features an ultra-ventilated design with over-injected flexible side wings that contour to the rider's body, ensuring freedom of movement and a secure fit. Its structural strength and load performance are achieved through a carefully engineered outer shell that balances durability with lightweight construction, making it ideal for aggressive riding conditions.
At the core of this protection system is the Nucleon Plasma back protector, constructed from viscoelastic, biobased polymers. Its pliable, impact-dissipating structure adapts to all riding positions while providing high-impact dispersion and absorption. The back protector*s ribbed, perforated lining enhances airflow against the skin, reducing heat buildup and increasing rider comfort during extended rides. The back and chest protections are complemented by adjustable, detachable rib and shoulder padding, offering customizable coverage against roost and impacts. The armor's construction includes adjustable shoulder and side straps that secure the protector in place, while removable soft thermoformed padding ensures a comfortable fit.
This model also features compatibility with the optional Race Kit, which allows for extended roost coverage with upper and lower chest extensions, and an additional Y-Strap System for compatibility with the A-4 chest without the back protector. The perforated 3D mesh chassis adds a layer of protection against tire roost and enhances overall airflow. Certified as eco-friendly and sustainable by USDA standards, the Alpinestars A-4 Plasma Roost Guard combines advanced impact absorption materials with thoughtful design. Whether tackling rough trails or competitive off-road events, this protector offers robust protection, ventilation, and comfort in a lightweight, durable package designed for serious riders.
Overall, the A-4 Plasma Roost Guard is a comprehensive solution for riders seeking maximum impact protection without sacrificing mobility or airflow, making it an essential piece of gear for off-road enthusiasts and racers alike.
