More than 10 years in the making, the Dainese D-Air Racing system is a new type of rider protection technology that uses a series of accelerometers and electronically operated rate gyros to deploy an airbag mounted in the aerodynamic hump of a leather racing suit when things go wrong on the racetrack. Taking only 40 milliseconds to trigger, the system provides protection for the neck, shoulder and collarbone, cushioning the falling rider before they hit the ground.
