Tech-Air® 3 Airbag System
Alpinestars Tech-Air® 3 Airbag System is an ‘over’ the jacket solution designed for commuters and younger riders and offers effective upper body protection by covering the rider’s full chest and full back. Featuring a water-resistant main chassis and a waterproof ECU and electronics, this slim, self-contained system can also be worn under a motorcycle jacket, including any Alpinestars’ compatible jacket, any leather or textile jacket, providing that the jacket has sufficient space to accommodate the inflation of the airbag. 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 activate the protective airbag in milliseconds, depending on the size of the airbag
