The jacket has a built-in inflatable bladder with a rapid deployment system that is composed of an oversized, pressurized CO2 cartridge, a firing pin, a key marble and a spring. When inflated, the airbag will protect the rider's torso, kidneys, lower back, back and shoulder blades and will prevent whiplash by creating an inflated collar around the helmet. After the airbag has been deployed, it can be deflated and rearmed by replacing the CO2 cartridge.
The key marble is linked to a security cord. When the rider is ejected from the motorcycle, the key marble is released and the firing pin pierces the CO2 cartridge by the spring. In one-tenth of a second, the released CO2 will inflate the air bladder, adding extra protection to the rider. Once the bladder is inflated, it will slowly deflate over a two and a half minutes.
Important Note: A 30 kg (60-pound) pulling force must be applied to the retaining key in order to activate the system. This helps to prevent accidental inflation of the vest when getting off your motorcycle while still attached to the leash.
