The Alpinestars Bionic Action Chest Protector provides ultra-lightweight upper-body protection against impacts while supporting ventilation, mobility, and a close-to-body fit. Its Cell Technology chest protector uses a highly perforated shell for breathability and protection, while the flexible side adapts to the rider’s body shape.
A new Cell Technology back protector features a flexion channel for enhanced mobility, with both front and rear hard-shell plates backed by bio-foam padding for a secure, comfortable fit. Extended padding helps protect against tire roost without obstructing arm movement, and the perforated protectors support cooling ventilation during use.
The thermoformed padded chassis is designed for comfort, while adjustable shoulder straps and removable shoulder pads allow fit and protection customization. An elastic closure system with quick, easy-to-use buckles fits a broad range of rider body sizes. The Alpinestars Bionic Action Chest Protector is compatible with Bionic Neck Support using the BNS A-Strap, available as an optional extra.
