Helite by the way makes a very nice touring style jacket with the bag built in.
Really like the idea of a jacket with the airbag built in. Put on your jacket/airbag and you're ready to ride. Helite, Alpinestars, Dainese, make some nice airbag jackets (probably several other brands, too). I choose the vest (Dainese) because I have several jackets that I like and felt like I didn't need another.
