Specifically the vest incorporates six sensors that measure acceleration and the rider’s position in space. The electronics monitor this data, and if the parameters exceed a threshold, the airbag can be inflated in 40 milliseconds in an effort to protect the rider’s frame (shoulders, chest, ribs, and entire back) before initial impact with the ground or obstacle. The Italian-American company claims the airbag is capable of reducing impact force by 93 percent compared to a passive chest/back protector.
