I was looking through potential options for dedicated one-piece suits, and I became interested in the airbag systems that are available nowadays. Wondering how many of you run one, be it an A* Tech-Air or Dainese D-Air, or any other external airbag system during races (I saw Gimoto makes one)? Do you find the extra bulk in your suit limits mobility or becomes uncomfortable during laps? Is the protective potential worth the hefty initial investment, considering these airbags alone cost the same as a halfway decent race suit? Any input from guys with more track time would be appreciated.
