Important Update: The Alpinestars Tech Air 5 System has been updated allowing for use on the street or the track. Riders are now able to switch from street to track using the Alpinestars App on their phone.
Tech-Air® 5 is a slim, self-contained wearable airbag vest designed to be worn under Tech Air Compatible Jacket, Tech Air Compatible Race Suit or any jacket with enough additional space to allow for a deployment. 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, and offering the most comprehensive coverage of any motorcycling airbag available today.
The state-of-the-art Tech-Air® 5 airbag system features six integrated sensors which continuously monitor acceleration and the rider's position. In the event of a crash, the system has a maximum inflation time of up to 40ms and the impact absorption while wearing the airbag results in a decrease of the impact force by up to 93 % compared to a passive protector. The airbag has been designed to deploy before the first impact with an obstacle, and in addition, protects riders in the event of a rear-end collision.
The system includes Bluetooth connectivity and comes with the Tech-Air® App, which uses the rider's phone to display the system's operational status, battery status and provides detailed analysis of a ride, in addition to over-the-air firmware updates. The airbag has a battery life of 30 hours of riding time on a single charge and an LED display conveniently shows system status directly on the garment.
Alpinestars recommends that there be approximately 4cm of room between the airbag and jacket across the entire circumference of the body (roughly the diameter of a golf ball). If wearing the airbag with a Tech Air compatible garment, this extra room is not necessary, as those garments are specifically designed to accommodate the inflation of an airbag.
It is important to note that this airbag is designed to be worn under a jacket, and not standalone. While the airbag provides impact and crash resistance, it does not provide abrasion resistance.
