Note: Read the entire user manual prior to operation. It is highly recommended that the Tech-Air 5 Plasma always be used together with a protective outer garment, as the Tech-Air 5 Plasma is NOT abrasion resistant. It can be used with any protective garment that covers the upper body and that is designed for motorcycle riding, provided that the garment has sufficient space to allow for the expansion of the airbag after the deployment. Not intended for use with heated riding gear. Heated gear exceeds the Tech-Air 5's upper operating limit of 122° F.
The Tech-Air series of autonomous airbag systems by Alpinestars are custom tailored for your type of riding. Whether your goal is going fast, commuting in the urban cityscape or exploring the road less traveled, Alpinestars has a Tech-Air autonomous airbag system for you.
A Lightweight Lifeline
The Tech-Air 5 Plasma's minimal material construction, streamlined profile, flexible Plasma back protector and single canister system make it 25% lighter than its predecessor and the lightest Alpinestars Airbag System to date. The system provides full upper body protection uniquely covering the rider's shoulders, which is critical in motorcycling accidents, in addition to the chest, ribs and full back. The integrated CE certified Level 1 Nucleon Plasma back protector is ultra-adaptive and provides the optimum balance of force dispersion, flexibility and comfort, so you can count on extra protection without the bulk.


Unrivaled Comfort
Designed to deliver an “invisible under the jacket feel,” the Tech-Air 5 Plasma Airbag System offers unrestricted movement and maximum breathability in addition to advanced protection. A super slim profile and adaptive stretch fit ensure superior comfort and range of motion. Thanks to the thoughtfully designed mono-layer stretch mesh construction at the collar, underarms and front of the body combined with extended mesh panels and moisture-wicking treatment, you’ll enjoy maximum ventilation and comfort that only the Tech-Air 5 Plasma can deliver.
High-Tech Made Easy
The system charges via USC-C and has a battery life good for up to 30 hours of riding time on a single charge. An integrated LED display conveniently shows the system status, riding mode and battery level directly on the garment.
The Tech-Air 5 Plasma features Bluetooth connectivity to pair with the Tech-Air App. The app uses your phone to display the system’s operational status, battery status and provides a detailed analysis of your ride with MyRide. Over-the-air software updates are also handled through the app.
