Alpinestars MX A-4 Plasma Chest Protectors

Alpinestars MXA-4 Plasma chest protectors are ideal for motocross, Enduro, and other off-road riders seeking a high-performance, low-profile chest protector that balances serious impact protection with exceptional ventilation and comfort, without the bulk of heavier armor. Alpinestars' chest protectors provide essential impact absorption and roost protection, shielding the chest and torso during intense rides. Designed to guard vital areas, these protectors minimize the risk of serious injuries from impacts, branches, and debris, making them a crucial addition for every rider. Each A-4 Plasma chest protector features breathable padding for comfort and is crafted to fit securely under or over your motocross riding jersey.

Key features, construction, and protection benefits:

* Anatomically profiled for all forms of off-road riding, the chest protector features a semi-rigid thermoplastic polyhedron design chest protector and a Nucleon Plasma back protector engineered to be lightweight, breathable, comfortable, adaptive, and protective
* Lightweight and ultra-ventilated chest armor—the chest outer shell's design is based on geodesic polyhedrons, and like a geodesic dome, less material is needed to achieve the desired structural strength and imposed load performance when compared to flat or unfaceted surfaces
* The Nucleon Plasma Back Protector is crafted from a USDA Certified Biobased viscoelastic material—designed for multi-directional pliability, the protector molds the body for a close fit, effectively dissipating impact energy to deliver reliable protection
* The lining on the back protector offers a soft tactile feeling against the skin while maintaining the integral structure of the protectors and reducing the risk of any material tearing
* Premium comfort—the over-injected flexible side wings of the chest protector perfectly follow the body's contours for superior comfort and freedom of movement
* Rib and shoulder coverage—the A-4 Plasma chest protector features highly perforated, adjustable, and detachable rib and shoulder padding for additional coverage against roost and impact
* BNS compatible via the elasticated BNS pull tabs situated on the removable soft tactile thermoformed shoulder pads Show Less
