Alpinestars Chest Protector with Airbag Tech-Air MX - White

The Alpinestars Tech-Air® MX System represents the highest level of active protection in motocross, enduro and rally riding. This advanced, fully autonomous airbag system integrates seamlessly into a compact chest and back protector, delivering unmatched protection for the shoulders, chest and back.

Thanks to its intelligent crash detection algorithm, developed using thousands of hours of data from MX and Supercross, the system reacts within milliseconds to a fall or impact. The airbag inflates extremely quickly for maximum impact absorption, without restricting your freedom of movement.

With multiple riding modes, configurable via the Tech-Air® App, the Tech-Air® MX fully adapts to your discipline — whether you ride off-road, race on the track or compete in rally events.

The lightweight, breathable design ensures optimal comfort and can be worn both under and over your motocross gear.
