I have a one x that is non airbag compatible, however they make/offer an airbag compatible one now. Ordering and designing was easy and communication from them was great. I would not rate this suit higher in quality or craftsmanship than something like RS Taichi, Daniese or Spidi, but I believe it is a perfect price point for what you get and I have no worries if I do crash it will hold up. Was really impressed with the gloves, the gloves seem to be top quality.
I did noticed there are many more one x suits in the paddock this year than last.
