The Ortovox Avabag Cartridge Carbon weighs just between 310 and 345 grams. It doesn’t get any lighter, smaller or more compact than this. The actual weight can vary within this range and is marked on each individual cartridge (note: this is the weight WITHOUT the protective cap). The weight should be checked before each use and may deviate by a maximum of +/- 5 g. If the deviation is bigger, it can affect the activation force and you should immediately exchange the cartridge free of charge!
