Discover unparalleled protection and cutting-edge technology with the Alpinestars Tech-Air® 3 Airbag Vest, the lightest autonomous airbag system designed for motorcyclists. Engineered to be worn over or under your motorcycle jacket, the Tech-Air® 3 is the ultimate choice for touring riders, urban commuters, and light off-road adventurers. Its advanced crash detection algorithm, honed through millions of kilometres of riding data and thousands of crash simulations, ensures precise deployment in dangerous situations like lowside or highside crashes.

In the event of a crash, the Tech-Air® 3 activates in just 50 milliseconds, providing critical protection ahead of impacts. It excels in "first impact" scenarios, inflating before the rider hits another vehicle or obstacle. Tested under the rigorous Dolomiticert Protocol, the system proves its efficacy at speeds ranging from 25 to 63km/h, ensuring riders are safeguarded in real-world conditions. The water-resistant main chassis and waterproof ECU make this system reliable in all weather conditions. Its slim, self-contained design means it can be comfortably worn under any motorcycle jacket with adequate space for airbag inflation (approx. 4cm), including Alpinestars’ Tech-Air® Ready jackets.

The fully autonomous Tech-Air® 3 requires no external connections or sensors, simplifying usage while maximizing protection. Six integrated sensors, including accelerometers and gyroscopes, provide optimal crash monitoring even in varied riding scenarios or when stationary. Activation is seamless with the magnetic zip closure, and when not in use, the vest’s packable design allows it to be conveniently stored in a backpack or under a bike seat.

Designed for ease and functionality, the vest features a diagonal zipper for full front chest coverage and a secure magnetic closure. An LED display on the chest shows the airbag’s operational status and includes a haptic alert for system arming and low battery notifications. The vest's advanced Pro 2nd Generation ECU, located in the upper back, connects via Bluetooth to the Tech-Air® App, allowing riders to monitor the system's status, battery life, and track rides with MyRide.

With a 40-hour battery life and a recharge time of just four hours, the Tech-Air® 3 ensures long-lasting performance. The inflator housing, located on the lower back, holds the gas inflator for rapid deployment. Designed to withstand all weather conditions, the vest meets European safety standards, offering Category II CE Certified full chest and back protection according to EN1621-4:2013 airbag regulations.

Experience peace of mind on every ride with the Alpinestars Tech-Air® 3 Airbag Vest, a revolutionary blend of safety, technology, and convenience.

*WARNING: This vest should not be used by people wearing a pacemaker or other electronic medical devices and people with breast implants. Remember that there are magnets inside the activation tab!

For example, if you wear a size L Neo Waterproof Hoodie, then the correct Tech-Air® 3 size for you should be a size L.
