Sizing Note: Tech Air 5 should only be worn UNDERNEATH a properly fitting Alpinestars Tech Air ready jacket or any jacket with 1.57" (4cm) of space around the circumference of the rider's chest.
Note: Read the entire user manual prior to operation. The Tech-Air 5 Vest is designed to 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 1.57" (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 1.57" (4cm) of space around the circumference of the entire body. Riders can also pair the Tech-Air 5 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.
Note: In the event of deployment of airbag, contact Alpinestars USA for west coast or Seacoast Sport Cycle for east coast. Detailed contact information can be found on the Instructions tab on the FAQ document on this product page. Pricing to repack the Tech-Air 5 is $175 USD per canister or $299 USD for canisters and bladder.

Everyday Comfort That Packs A Punch
The Tech-Air 5 Airbag System is a slim, self-contained wearable airbag vest designed to be worn under virtually any jacket. The system provides unrivaled 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 Tech-Air 5 is designed for the track and street, so you'll be protected wherever the road takes you.


State-Of-The-Art Technology
The state-of-the-art Tech-Air 5 System features six integrated sensors (3 gyroscopes and 3 accelerometers) to continuously monitor the rider’s position. An algorithm developed closely with MotoGP race data and data from over 2,000 lab-simulated crash scenarios determine when and how the system deploys.
The airbag has a maximum inflation time of up to 40ms (or less, depending on vest size). The impact absorption while wearing the airbag results in a decrease of impact force by up to 93% compared to a passive chest or back protector. Inflation time is quick enough to deploy the airbag before the rider's first impact with an obstacle. In addition, the vest will protect stationary riders in the event of a rear-end collision.
No Fuss
The airbag has a battery life good for 30 hours of riding time on a single charge. An LED display conveniently shows the system status directly on the garment. Alpinestars includes a micro USB charger for quick recharging.
The Tech-Air 5 features Bluetooth connectivity to pair with the Tech-Air App. The app uses the rider’s phone to display the system’s operational status, battery status and provides a detailed analysis of your ride. Over-the-air firmware updates are also handled through the app.
