Alpinestars Tech Air 3 Lightweight Airbag vest ::

Alpinestars Tech Air 3 System

Alpinestars’ lightest autonomous Airbag System, Tech-Air® 3 is designed to be worn over or under the motorcycle jacket, as the effective and practical choice for touring riders, urban city commuters and light off-road adventure riders.

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 50 milliseconds. In the event of a direct impact of the motorcycle with another vehicle or obstacle, the Tech-Air® 3 System, is effective for the “first impact,” which means that the System inflates before hitting the vehicle or obstacle against which the motorcycle will have the direct impact. The “first impact” test was performed in accordance with Dolomiticert Protocol where the airbag was tested within a speed range of 25 to 63 km/h. For more information on the envelope of protection, see the Tech-Air® 3 User Manual.

Featuring a water resistant main chassis and a waterproof ECU and electronics, the slim, self-contained system can also 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. Tech-Air® 3 will allow riders to enjoy the daily commute even more, knowing they’re protected.

Key Features

  • Tech-Air® 3 is a fully autonomous active Airbag System and does not require any external connections or sensors on the motorcycle for the System to operate.
  • Tech-Air® 3 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 Airbag System activates automatically via the magnetic zip closure.
  • The System’s packable design allows it to be easily stored in a backpack or under a bike’s seat when not in use.

Our Two Cents

The Tech-Air® 3 system is Alpinestars latest and greatest airbag system designed for toruing and commuter riders. The Alpinestars Tech-Air® 3 airbag vest is versatile enought to perform either over or under your riding jacket/suit. It uses same algorithm as the Tech-Air® 5 system.

When you put the Tech-Air® 3 system on, there are several magnets and attachments to take note of. First, the base of the zipper mates with the other side easily thanks to a magnet that lines it up perfectly on the first try. There is a fabric flap that overlays this end of the zipper and stays in place with another magnet, protecting your tank from zipper scratches. Further up the main opening the chest portion of the airbag connects to the left side of the chest with a magnetic button that holds it in place. When you fully close the diagonal main zipper another magnet near the top activates the system. This magnet is part of the LED display, which also has a haptic alert that vibrates when it arms and also when the battery is low.

The Tech-Air® 3 system protects the full chest and full back. The “brains” of the system are housed in a waterproof container on the rear left of the jacket. It’s kind of bulky, but once you have the system zipped closed it rests comfortably in place. You can also add a passive back protector in the pocket that can be accessed via zipper on outside of the garment (see related products below). Since the Tech-Air® 3 system is designed to be worn over or under another jacket they haven’t included the back protector here. Also, the Tech-Air® 3 system works as a CE level 2 back protector when deployed but if for some reason it doesn’t deploy you’re going to want that passive armor. Their is a small zippered storage pocket on the right side of the belly as well.

The Alpinestars Tech-Air 3 Airbag Vest is designed for touring riders and urban commuters. Alpinestars provides some conflicting information on off-road use, at one point saying it is good for “light off-road adventure riders” and later saying that it is not suited for off-road. I’d take this to mean if you’re on a maintained road you’ll probably be fine but if you ride in conditions that get into aggressive angles or loose pack that kicks the rear end out unexpectedly then you might have an accidental activation. So off-road adventure riders beware.

Overall the Alpinestars Tech-Air® 3 system is a great versatile airbag option for touring and urban riders. We’re excited to see Alpinestars continue to expand their airbag lineup and innovate in this advanced form of protection that ultimately saves lives and brings more riders into our sport. :: Mike, 12/15/2022
