Alpinestars Tech-Air 5 System
Tech-Air 5 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, critical in motorcycling accidents, in addition to the chest, ribs and full back. The Tech-Air 5 Airbag System offers the most comprehensive coverage of any motorcycling airbag available today.
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 95% 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.
The airbag has a battery life good for 30 hours of riding time on a single charge, and an LED display conveniently shows system status directly on the garment. The system features Bluetooth connectivity to pair with the Tech-Air App, which uses the rider’s phone to display the system’s operational status, battery status and provide detailed analysis of a ride. Over-the-air firmware updates are also handled through the app. Alpinestars includes a micro USB charger for quick recharging.

Note: 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 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 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.
