The ABS Avalanche Airbag is an intelligent system used to prevent complete burial in an avalanche and to survive the accident as unharmed as possible.
The rescue concept: with one pull on the activation handle of the backpack two airbags will inflate in mere seconds to a total volume of 170 liters. This additional volume will likely prevent the burial of the carrier. Gas from a cartridge contributes to the airbag filling. Of course the ABS Airbag can be re-used after activation. The cartridge as well as the activation handle can be re-filled.
98%* off all avalanche victims with activated ABS-Avalanche Airbag survived nearly unharmed.
