Airbag vest Alpinestars Tech-Air 3 V2

The Alpinestars Tech-Air 3 V2 airbag vest is an advanced autonomous motorcycle airbag system engineered to deliver premier upper-body protection on every ride. Specifically developed for daily commuters, touring riders, and light adventure enthusiasts, this protective vest operates independently without external bike sensors. Using advanced crash-detection algorithms, the system inflates the protective airbag within 50 milliseconds upon detecting a collision or fall, shielding critical areas such as the chest and back before initial impact. Featuring a water-resistant chassis and a waterproof central control unit, it can be worn comfortably over or underneath any textile or leather riding jacket with sufficient expansion space. The high-visibility fluo yellow and black colorway significantly enhances road presence in low-light conditions. Wear this vest for optimal comfort on the bike paired with properly fitted protective riding gear.
