Alpinestars A-5 Plasma Chest Protector | Black/Red/White

The Alpinestars A-5 Plasma Chest Protector delivers advanced impact protection with maximum ventilation — engineered for motocross, enduro, and off-road riders who demand both safety and comfort.

Built around a highly perforated 3D mesh shell, the A-5 Plasma promotes superior airflow while the Nucleon Plasma viscoelastic material — a bio-based polymer — absorbs and disperses impact energy across the chest and back. Independent side wings conform to your body for a fully adaptive fit, while a composite back protector with a semi-rigid thermoplastic zone targets critical impact zones.

Adjustable shoulder and side straps, removable thermoformed shoulder padding, and BNS-compatible shoulder pull tabs make this protector as versatile as it is protective.
