Alpinestars Tech-Air 3 System Resources

Alpinestars Tech-Air 3 System

The Tech-Air 3 System from Alpinestars is a game-changer for city commuters and street riders seeking advanced protection. This autonomous airbag system is Alpinestars' featherweight marvel, easily worn beneath or over your jacket for ultimate riding comfort. Powered by the cutting-edge Tech-Air 5 Street crash detection algorithm, driven by AI, it stands vigilant to deploy the airbag precisely when needed. Equipped with six integrated sensors, it excels in monitoring crashes and offers active airbag protection in various dynamic street riding scenarios.
The Tech-Air 3 doesn't just react; it anticipates dangers, activating the airbag in milliseconds, tailored to the situation's gravity. Once deployed, it blankets your upper body, covering chest and back. You can even add an extra layer of safety with a separate back protector. Plus, an LED display and haptic alerts keep you informed, and Bluetooth connectivity to the Tech-Air App provides detailed ride data, ensuring a secure and connected ride.

Electronics System:

  • Incorporates 6 integrated sensors (3 accelerometers, 3 gyroscopes or 1 triaxial gyroscope and 1 triaxial accelerometer) to provide the best crash monitoring performance in a variety of dynamic riding situations
  • Activates automatically via the magnetic zip closure
  • ECU and electronics are located in a waterproof housing for proven wet weather performance
  • Incorporates Alpinestars’ Pro 2nd Generation compact Electronic Control Unit (ECU) embedded in the upper back of the vest
  • Uses the Tech-Air 5 street algorithm which provides active protection in street riding scenarios and a variety of riding conditions, even when stopped
  • Upgradable system firmware, accessible via the Tech-Air App
  • Bluetooth low energy (BLE 5.0) connectivity with the Tech-Air App shows the system’s status, the battery status and riding data
  • Integrated, certified lithium ion battery, with a battery life of 40 hours and a recharge time of approximately 4 hours

Airbag System:

  • Fully autonomous active airbag system
  • Strategically positioned stretch panels on both sides of the abdomen to accommodate the expansion of the airbag in the event of a crash
  • Argon gas canister that provides the inflation gas for the airbag’s deployment is housed in an ergonomic case on the right side of the lower back of the rider


  • LED display on the front chest continuously indicates the airbag’s operational status
  • LED display incorporates a haptic alert, which vibrates to confirm the system is armed and alerts the rider when the battery is running low
  • Equipped with a diagonal zipper to provide complete front chest coverage while also concealing the inner airbag
  • Internal magnetic button facilitates easy positioning of the airbag across the chest when riding

Additional Features:

  • Chassis is constructed with a water resistant treatment for effective all-weather performance
  • Perforated back zone for improved breathability, with internal air channels for enhanced airflow
  • Integrated back protector pocket (back protector sold separately)
  • Canister housing, electronic wiring and airbag are easily removable
  • Packable design for easy storage when not in use
  • Washable

Sizing Note: Alpinestars warns that any Tech-Air 3 System smaller than size SM must not be worn under your jacket and should only be worn OVER your jacket.

Note:  The Tech-Air 3 Vest can be worn under any properly fitting textile jacket, keeping in mind that the jacket must be large enough to accommodate the expansion of the airbag in the event of a crash. For textile jackets, riders need 4cm of additional space around the circumference of the body. Riders who wish to wear a leather jacket that is not Tech-Air compatible must be sure that the leather jacket has an additional 4cm of space around the circumference of the entire body. Riders can also pair the Tech-Air 3 Airbag Vest with any Alpinestars Tech-Air compatible jacket that features airbag expansion panels. Not intended for use with heated riding gear. Heated gear exceeds the Tech-Air 5's upper operating limit of 122° F.
