Alpinestars Tech-Air® 3 Leather Airbag Vest V2

Classic leather. Futureproof protection.

** With this Tech Air Vest, you can replace the te yourself 

The Tech-Air® 3 Leather Vest is Alpinestars’ most refined take on smart airbag safety, wrapped in premium cowhide for riders who want that timeless leather look without compromising on high-tech performance. Whether you’re navigating the urban grind, out on a weekend escape, or just want peace of mind on every ride, this self-contained system’s got your back (and chest).

It’s a fully autonomous airbag vest, no wires, no sensors on your bike, powered by six internal sensors and a next-gen crash detection algorithm trained on thousands of real-world impacts. In a split-second, it inflates before a crash to reduce up to 95% of impact energy across the upper body. That means serious protection, minus the bulk.

Made to wear over any jacket, the leather version adds that clean, classic edge, finished with ribbed stretch panels and breathable perforations so you don’t sacrifice comfort for safety.
