Just wondering if any of you guys have rode or crashed in an airbag vest, and what has been your experience? Do you think they're worth the investment? The AStars and Dainese systems look really nice, but I hate the fact you need to send them back to the manufacturer to be repacked after they've been deployed, and the price they're charging you for that service! So it looks like one of the tethered vest options might be a better choice for me, if I decide to go that route. The two track specific vests I'm considering are the Hit-Air RS1 and the Helite Air track vest. The Hit-Air is about $400 cheaper, but looks to me like it lacks some back protection, whereas the Helite looks to have that protection and is make out of 1.2mm leather, but is a lot more expensive. Does anyone have any experience/opinions with either one of these vests? I'm wondering which one is more commonly used at the track. I really appreciate any advice you guys can give me! Thanks again!
