Crafted with an anatomically profiled semi-rigid thermoplastic polyhedron chest protector, it ensures a secure fit and enhanced impact resistance. The highly ventilated, lightweight construction promotes airflow to keep riders cool during intense riding sessions while maintaining durability and structural integrity. The chest shell’s design balances strength and flexibility, following the body's contours for maximum comfort and freedom of movement. The over-injected flexible side wings adapt seamlessly to the rider’s body, enhancing comfort without compromising protection. Equipped with adjustable shoulder and side straps, the guard offers a tailored fit that optimizes performance and safety, making it suitable for a variety of off-road disciplines. The removable soft thermoformed shoulder padding adds an extra layer of comfort, reducing fatigue and chafing during extended rides. The back protector, made from viscoelastic, biobased polymers, is engineered for impact absorption and energy dissipation, forming a pliable yet protective barrier that conforms to the rider's movements. Its ribbed lining improves airflow and minimizes skin contact, reducing the risk of chafing and overheating. The perforated 3D mesh chassis further enhances ventilation and offers additional protection against tire roost and debris. For riders seeking customization, the optional Race Kit extends coverage with upper and lower chest extensions and an additional Y-Strap System, allowing use of the A-4 Chest without the back protector. Compatibility with Bionic Neck Support via BNS shoulder pull tabs provides added safety for high-impact riding. Constructed from USDA certified bio-based eco-friendly materials, this gear combines sustainability with high-performance impact absorption, making it an environmentally responsible choice for off-road enthusiasts looking for reliable protection with maximum comfort.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eAnatomically profiled semi-rigid thermoplastic polyhedron chest protector for optimal fit and impact resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHighly ventilated and lightweight design promotes airflow and rider comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eImpact-dissipating Nucleon Plasma back protector made from biobased, viscoelastic polymers for pliability and energy absorption\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFlexible side wings contour to the body for enhanced comfort and unrestricted movement\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable shoulder and side straps for a customized, performance-oriented fit\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRemovable thermoformed shoulder padding increases comfort during extended rides\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePerforated 3D mesh chassis provides additional protection and airflow against roost and debris\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOptional Race Kit includes chest extensions and Y-Strap System for increased coverage and versatility\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with Bionic Neck Support for added safety in high-impact riding scenarios\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstructed from USDA certified bio-based eco-friendly impact-absorbing materials for sustainability\u003c\/li\u003e\u003c\/ul\u003e\n\u003cbr\u003e\u003cdiv class=\"product-template\"\u003e\n\u003cbr\u003e      \u003ch1\u003eAlpinestars A-4 Plasma Roost Guard – Black, Red \u0026amp; White, Medium\/Large – Part Number 6500526-132-ML\u003c\/h1\u003e\n\u003cbr\u003e      \u003cp\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003eThe Alpinestars A-4 Plasma Roost Guard is designed to provide superior protection and comfort for off-road riders.
