Built from decades of race-winning experience, the Alpinestars A-4 Max Chest Protector delivers serious upper body protection without sacrificing comfort or mobility. Flexible hard plates shield the chest, ribs, and back, while a new triple-layer chest protector with a highly perforated impact-absorption insert and Cell Technology back protector provide excellent impact dispersion and airflow. Ventilated bio-foam padding and perforated shells keep the protector cool and comfortable, even during intense motos or long trail days.

With removable shoulder pads, extended side and lower padding, and adjustable elastic straps that include thermoformed rib protection, the A-4 Max offers customizable coverage to match your riding style. The thermoformed padded chassis wraps the torso for a close-to-body fit, and full compatibility with Alpinestars Bionic Neck Supports makes it a smart choice for riders who want to step up their safety without adding bulk.
