Alpinestars Tech-Air 3 Lightweight Airbag Vest
Men's - Black / # 4498-0055-xx

If you're a city commuter or street rider looking for an added layer of protection, look no further than the Tech-Air 3 System from Alpinestars. It's the lightest autonomous airbag system offered by Alpinestars and it can be worn under or over your jacket, so you can ride comfortably. The cutting edge Tech-Air System uses the Tech-Air 5 Street crash detection algorithm that leverages AI to accurately monitor when to deploy the airbag in the event of a crash. The Tech-Air 3 incorporates six integrated sensors to provide the best crash monitoring performance and active airbag protection in a variety of dynamic street riding scenarios, even when stopped.

The Tech Air 3 System accurately assesses when to deploy the airbag ahead of an impact or other dangerous situation like a lowside or a highside crash. The system will activate the protective airbag in milliseconds depending on the size of the airbag. Once inflated, the airbag provides full upper body protection, keeping you safe by uniquely covering your full chest and back. The Tech-Air 3 features an integrated back protector pocket so you can insert a back protector (sold separately) for an additional layer of safety. An LED display on the front chest indicates the airbag's operational status and incorporates a haptic alert which vibrates to confirm the system is armed and alerts you when the battery is running low. Bluetooth connectivity to a Tech-Air App allows you to monitor the Tech-Air 3's operational status, battery status and detailed map of your ride.
