Product Details
The Alpinestars Tech-Air 3 V2 is a low-profile, fully autonomous motorcycle airbag system for road touring, commuting and light off-road riding. This Black / Fluo Yellow version can be worn over a motorcycle jacket or beneath a compatible jacket that provides enough room for the airbag to inflate.
Because the system is self-contained, it does not need sensors or a tether fitted to the motorcycle. Alpinestars' crash-detection algorithm monitors the ride and, when it detects the start of a crash, can fully inflate the airbag in approximately 50 milliseconds to protect the upper body.

Size and jacket compatibility
This listing is available in XS, S, M, L, XL, XXL, 3XL and 4XL. Select the system size using Alpinestars' current sizing guidance. If you plan to wear it beneath a jacket, that garment must provide sufficient expansion space for inflation. A Tech-Air Ready jacket is suitable, while another leather or textile motorcycle jacket may also be used when its fit and expansion allowance are appropriate.
Airbag-system fit and jacket compatibility are important. Moto Central can help you check both at our Leicestershire showroom before purchase.

Questions and answers
Does it need to connect to the motorcycle?
No. The Tech-Air 3 V2 is a fully autonomous system with no bike-mounted sensors or tether.
Can it be worn beneath any motorcycle jacket?
Only when the jacket is compatible and has sufficient room for the airbag to inflate. Check the complete combination rather than relying on the jacket label alone.
Is the whole vest waterproof?
Alpinestars describes the textile main body as water-resistant. The electronic components are enclosed in a waterproof, impact-resistant housing.
