It seems like everyone is taking the airbag route now, and Motoairbag are the latest group to have a go with their spinal cord protecting waistcoat.
Called the Motoairbag, the jacket is worn like a normal motorcycle jacket over the top of your normal kit. The airbag is attached by a cable to a clip on a ring of a special belt that goes onto the bike seat.
Once the cord comes away from the ring the suit is activated. Check the demonstration video below to see how it works.
