Here's what other sites are saying:
The Mammut Light Removable Airbag is the absolute featherweight among their avalanche airbags. With the Removable Airbag System without a cartridge, the avalanche airbag weighs around just 1930 kg. However, it still delivers all the features you would expect from a good one-day touring or freeriding backpack. High comfort and a range of attachment options. Pack only, no airbag/engine or cylinder.
