Travelling With Avalanche Airbags

Avalanche airbags have gained popularity recently as more and more people venture off piste, however as the compressed gas cylinders they use are classed as hazardous goods, so travelling with them can be difficult.

As they are becoming more popular airlines and airport security are becoming more used to dealing with them. Unfortunately the system is not perfect..... yet.

So here is everything you need to know about travelling with an avalanche airbag.


Flying with an avalanche airbag


It is possible to transport avalanche airbags by air. The main issue is with the pressure cartridges used in avalanche airbags which are classed as hazardous goods. Special regulations therefore apply if you wish to carry them with you on a flight. On the other hand, the backpacks, and the individual airbag systems (excluding the cartridge), can be transported separately without any problem.

Transportation of the pressure cartridges is governed by the International Air Transport Association (IATA). In normal circumstances, individuals are not permitted to carry hazardous goods on board an aircraft. However, airbag pressure cartridges are covered by a special IATA regulation permitting one cartridge per person. These special regulations are recorded in the IATA Table 2.3A.


IATA approval:

Avalanche airbags and cartridges may be transported (Cartridge Non-Refillable 300 Bar Steel, Carbon Cartridge Non-Refillable 300 Bar, Cartridge Refillable 207 Bar Alu) subject to the following conditions:

  • One avalanche airbag and one cartridge per person - The pressure cartridge must be filled with Class 2.2 gas (all Mammut cartridges are filled with Class 2.2 gas)

  • The pressure cartridge may not be transported separately from the avalanche airbag. The cartridge must be transported in the avalanche airbag compartment provided. It must be packed in a manner that prevents accidental activation (cartridge must not be screwed into the airbag system). The airbag must be fitted with a pressure release valve (all Mammut airbag systems are fitted with a pressure release valve).

  • The airline’s approval is required – Before booking your flight, inform the airline operator that you plan to take a cartridge on board. Send the airline the appropriate cartridge data sheet in advance, together with the extract from the IATA-2.3A table. IMPORTANT: Despite the IATA’s approval, any airline operator is entitled to refuse to transport the cartridge.

We recommend transporting the avalanche airbag as carry-on baggage. Before doing this, place the cartridge in the avalanche airbag compartment provided. Screw the protective cap onto the cartridge before transporting it. Insert the cartridge with a printout of the cartridge data sheet and IATA-2.3A table and a copy of your airlines policy regarding airbags.


Special regulation for the USA & Canada

The Transportation Security Administration (TSA) does not permit the carrying of filled pressure cartridges on flights arriving into or departing from the USA, or on internal flights within the USA. This regulation also applies to passengers transferring between flights in the USA. The TSA regulation can be found here: compressed-gas-cylinders

Customers with these bags are recommended to hire a cartridge locally during their stay in the USA. A list of cartridge rental stations can be found here: Mammut Cartridge Rental.



There is often confusion regarding the use of Compressed gas canisters in airbags in Japan. The issue is around the refillable cartridges only.

Japan uses a different system to refill compressed gas which is not compatible with the refillable cartridges sold to USA and Canadian customers due to the TSA regulations. The non-refillable carbon cartridges are available in stores in Japan should you require a replacement.
