Choosing an avalanche airbag

When exploring avalanche-prone backcountry, using an avalanche airbag can be lifesaving. With rapidly changing technology, new safety standards, and specific needs, selecting the right avalanche airbag backpack requires some guidance.

To choose the best avalanche airbag, you'll need to think about:

  • Body fit and activity

  • Deployment system

  • Pack volume

  • Airline and travel rules on gas cylinders and batteries

  • Compatibility with your other avalanche safety gear

What is an avalanche airbag?

Avalanche airbags prevent burial when caught in an avalanche. Airbag systems are built into backpacks and allow the wearer to inflate large airbags in a matter of seconds with the pull of a handle.

How do avalanche airbag backpacks work?

Avalanche airbag packs increase your volume and keep you on top of an avalanche rather than getting buried underneath.

The airbag is stowed in a specific compartment in the pack. It's triggered by pulling a handle. This initiates the system mechanism, causing the airbag to inflate. Negative pressure draws extra air into the primary flow, helping to fill the airbag in seconds.

Why use an avalanche airbag?

Avalanche airbags greatly increase survival rates in snowslides compared to standard packs alone. However, they are not a guarantee of survival; they are a complement to training, situational awareness, and carrying a beacon, shovel, and probe.

System types

Avalanche Airbag Pack Types

Compressed Gas (Canister) Systems

  • Use canisters of compressed gas to fill the airbag.

  • Once triggered, the gas rapidly inflates the airbag.

  • There are single-use and refillable canister systems which can be refilled at specific centres

Electric Fan (Battery-Powered) Systems

  • Use a rechargeable battery to spin a high-powered fan, inflating the airbag.

  • Multiple deployments are possible on one charge, and easier international travel (no cartridge regulations).

Image of Capacity

Capacity

Consider what type of skiing you will be doing and then align the capacity of your chosen pack with your intended use. For example, heli-accessed sessions or freeriding near lift accessed terrain requires you to carry less kit than if you were heading out on a full day tour into the backcountry.

Equipment carry options

Different packs will have different features; from ski carry options to helmet nets and avalanche safety gear pockets. Your requirements will be led by your intended use as well as personal preferences; make sure the pack you choose has the options that you want.

Image of Size & fit

Size & fit

As with any technical backpack, it needs to fit well and be comfortable to carry. On some models, the position of the airbags after inflation is important, so it is vital to get a pack which fits your torso correctly. A well-fitted backpack will also ensure the correct positioning of the trigger handle; so that it is easy to reach and pull. If size options are available, make sure you check out size guides to get the right fit. Where possible, we recommend heading into one of our stores where our staff can help you select the right model.

Image of Weight

Weight

For longer tours and lots of up-hill work, choosing the lightest pack possible will be very attractive. However, lighter weights generally come at the cost of durability and features, so it is all about compromise. If you are planning to spend more time going down than up, then you may prefer to carry some extra weight in return for a burlier pack that can take a bit of abuse.
