It's some kind of an Airbag System that can help popping out on top of an avalance when she comes to a stop. One Manufacturer of these Bags is “ABS“. There are other Manufacturers like “Snowpulse“ that is now running under “Mammut“. Or “BCA“ from the States. I heard also Black Diamond is working on such a System. At the moment I would recommend a Mammut. They have a low price and a super performance. Next winter with many different Packpacks.
