Only airbag that I know of that is designed specifically with snowmobiling in mind is the BCA Throttle (a redesigned Float 22), though its new, BCA has a good rep with past airbags, so should be a good item.
Air cylinders are swappable among the different BCA packs as well, which is nice, not to mention the ease of refill, can even look up approved BCA refill locations at: http://www.backcountryaccess.com/about/map2/ (choose "Refill Center" from the BCA Dealer Type drop down)
