Alpinestars Airbag TechnologyThe first consumer implementation of airbags into a leather suit was specifically designed for road racers. These airbags are concentrated on the neck and shoulders, which is the most common injury during a road race crash. The airbags are placed inside each shoulder pad with the electronic 'hub' slotted into the neck hump. This tucks it out of view and only adds 500 grams of weight to the suit. This is in comparison to Dainese's similar D-air suit which weighs between 700-750 grams.
