Alpinestars’ crash detection triggering algorithm has been developed and refined with millions of kilometers of riding data and thousands of crashes, allowing the System to accurately assess when to deploy the airbag ahead of an impact or other dangerous situation like a lowside or highside crash.

In the event that Tech-Air 3 detects the start of a crash, the System will inflate the protective airbag in milliseconds, reducing up to 95% of the impact energy transferred to the rider anywhere the airbag protects, which includes the full chest and back.

In the event of a direct impact of the rider with another vehicle or obstacle, the Tech-Air 3 System, is effective for the “first impact1,” which means that the System inflates before the rider hits the vehicle or obstacle against which the rider will have the direct impact.

Featuring a main chassis constructed with premium softened leather, and waterproof ECU and electronics, the slim, self-contained System can be worn under a motorcycle jacket, including an Alpinestars’ Tech-Air Ready jacket, or any leather or textile jacket, providing that the jacket has sufficient space to accommodate the inflation of the airbag.

Features: 

• The Tech-Air® 3 Leather System is a fully autonomous active Airbag System and does not require any external connections or sensors on the motorcycle for the System to operate.
• The Tech-Air® 3 Leather incorporates 6 integrated sensors (3 accelerometers (1 triaxial accelerometer), and 3 gyroscopes (1 triaxial gyroscope)) to provide the best crash monitoring performance in a variety of dynamic riding situations, and even when stopped.
• The Tech-Air® 3 Leather Airbag System uses a crash detection algorithm that leverages AI to accurately monitor when to deploy the airbag in the event of a crash, allowing the airbag to provide active protection in street riding scenarios and a variety of riding conditions, even when stopped.
• The Tech-Air® 3 Leather Airbag System activates automatically via the magnetic zip closure.
• The System’s packable design allows it to be easily stored in a backpack, saddle bag, top case or pannier, when not in use.
• The Tech-Air® Leather System’s design incorporates added functionality including a built-in sunglasses pocket on the right chest, a waist loop where you can attach riding gloves, elasticated side panels for comfort that provide expansion volume to accommodate the inflation of the airbag, and a convenient option for you to easily fold and button away the airbag bladder.
• The vest has 2 zippered hand pockets, 2 zippered chest pockets, as well as an inner pocket for convenient storage.
• The Tech-Air® 3 Leather System’s vest construction provides openings that will allow riders to customize their vest with patches or embroidery if desired.
• An LED display, partially hidden inside the left chest pocket, indicates the airbag’s operational status. The pocket has a reflective inner backing for optimized LED visibility and also incorporates a haptic alert, which vibrates to confirm the System is armed, as well as alerts the rider when the battery is running low.
• Integrated back protector pocket on the back can house additional passive back protection.
• Tech-Air® 3 Leather incorporates Alpinestars’ Pro Second Generation compact Electronic Control Unit (ECU) which may be found in the ECU pocket located in the upper back of the Tech-Air® 3 Leather vest.
• Bluetooth low energy (BLE 5.0) connectivity to the Tech-Air® App allows riders to monitor the System’s operational status, battery status, as well as provides a detailed map of motorcyclists rides via MyRide.
• Upgradable System software is accessible via the Tech-Air® App, where riders can quickly verify the installed software version and easily perform the latest software updates.
• Tech-Air® 3 uses an integrated, certified lithium ion battery, a fully charged battery will provide the System with 40 hours of active ride time. A low battery will fully charge in about 4 hours; charging the battery for approximately 1 hour will provide about 8-10 hours of riding time.
• The gas inflator that provides the inflation gas for the airbag’s deployment is located in the inflator housing on the left side of the lower back of the rider.
• The gas inflator housing, electronic wiring, and the airbag are easily removable.
• The gas inflator canisters can be replaced by select Alpinestars dealers and certified Tech-Air® Service Centers, or by yourself at home.
• The Tech-Air® 3 Leather vest is not washable; do not wash it with water, bleach, or put it in the dryer, iron it, or dry clean it. We recommend using a damp cloth to remove dirt or flies. For detailed care and cleaning procedures, please refer to the User Manual.

*Note, technically the Leather and Canvas Tech-Air 3 options came out in 2024, but these V1 models were not user serviceable, and some of the leather options in particular had issues with their magnetic zipper switching lining up consistently. Going forward we’ll only be carrying the V2 versions, although as of this posting there are a few V1 Canvas models up for closeout.
