An avalanche airbag pack is a valuable addition to a safety system that works if used properly, if it deploys, if it stays inflated, if trauma is not too severe, if you are not hit by the avalanche from above, if you are not buried in a terrain trap, if the avalanche is not too large, and so on.

How much do avalanche airbags help?
