I've been very happy with my "Hit-air" brand jacket.
It provides me a greater sense of security; not that I ever hope to need it. Five bills
Looks good Gordon!
It was a toss-up between Hit-Air and Helite airbag systems for me, both of which are mechanically activated. No batteries charge or activation lights to monitor...falls into the KISS philosophy IMHO. Helite price point was higher but they probably did a better job with their marketing or maybe the demo girls on the videos were just a tad prettier, ha! Lol.
However, one cannot go wrong with either system as they so closely comparable in terms of the technology used and the protection both provides. Lastly, most motorcyclist are worried about accidental activation with these systems where one forgets to unhook from the teether. From what I have read from both the manufacturers and current owners, it is not a common occurrence since it takes a about 30 or so lbs of force to activate and one will get an initial tug if one forgets to unhook before dismounting (Gordon, you can validate this if you wish). In any case, in the unlikely event it does get inadvertently activated, reloading is a simple process of installing a new CO2 canister.
Initially, I was drawn towards the AlpineStars and Dainese sensor/electrically activated airbags. Both were pretty impressive but after much analysis, I decided to go mechanical vs. electrical. Just FYI, once any of these two airbag systems are activated, both require a return to the manufacturer or dealer for a complete check and reload of new canister...at a cost of a few hundred bucks.
