The Ortovox AVABAG System Carbon Cartridge is used in conjunction with the Ortovox Ascent 30L AVABAG System to keep you safe in the event of an avalanche. It is light, small and compact, you won't even notice it in your avalanche bag. The canister is easy to install and can be removed quickly. It can inflate in around 3 seconds as time cannot be wasted during an avalanche. Carbon is stronger and more durable than many other materials once it has been treated with electro-thermal purification technology.
