Alpinestars Bionic Action Chest Protector – Lightweight, CE-Certified Off-Road Protection (M/L, Black/Red)

Meet the Alpinestars Bionic Action Chest Protector, an ultra-lightweight protective system built for off-road riding. It combines a next-generation chest protector with an highly perforated shell, delivering cooling ventilation without sacrificing protection. This setup helps you stay focused on the trail while maintaining a light, unobtrusive feel on the chest.

Ventilation and comfort begin with the front shell, engineered with Cell Technology to maximize airflow and protection. The flexible side panels adapt to your body shape, helping the protector stay close without pinching or bunching. For riders seeking a tailored feel, removable shoulder pads offer customization without compromising safety or comfort.

The back protector is new and uses a softer formulation for an adaptive fit. Both the front and rear hard shell plates are backed with bio-foam padding, delivering a secure, snug feel that moves with you. A thermoformed chassis provides a close-to-body profile, reducing bulk under gear while preserving a solid protective structure for uneven terrain.

Usability is a key part of the design. The Bionic Action Chest Protector is quick and easy to put on, then adjusted for a secure fit that doesnt restrict arm movement during aggressive turns or long rides. Extended padding helps shield against tire roost and kicked-up debris, while still leaving you free to reach, maneuver, and ride with confidence.
