Sizing Note: Alpinestars warns that any Tech-Air 3 System smaller than size SM must not be worn under your jacket and should only be worn OVER your jacket.

Note: The Tech-Air 3 Vest can be worn under any properly fitting textile jacket, keeping in mind that the jacket must be large enough to accommodate the expansion of the airbag in the event of a crash. For textile jackets, riders need 4cm of additional space around the circumference of the body. Riders who wish to wear a leather jacket that is not Tech-Air compatible must be sure that the leather jacket has an additional 4cm of space around the circumference of the entire body. Riders can also pair the Tech-Air 3 Airbag Vest with any Alpinestars Tech-Air compatible jacket that features airbag expansion panels. Not intended for use with heated riding gear. Heated gear exceeds the Tech-Air 5's upper operating limit of 122° F.
