The Ortovox Avabag Cartridge Carbon weights 310 grams. It is super light, small and compact.
The cartridge is super easy to install and take out.
Ortovox came to life when Gerald Kampel and Jürgen Wegner developed the first double frequency transceiver to aid in avalanche victim searches. They have since grown into one of the biggest producers of avalanche safety gear on the market. In 1995 they added merino underwear to their selection, and we have been hooked ever since!
