Electric or cartridge avalanche airbag? We compare how each system inflates, what a reset costs, and why a full cartridge can't fly into or within Canada, so you can pick the one that fits how you ski.
You're looking at a $1,900 backpack and wondering whether it does anything. It's a fair question, and the honest answer is more interesting than either the marketing or the internet arguments suggest. Avalanche airbags work, and the largest study of real accidents found they roughly halve mortality. But the size of that effect is smaller than most people assume, and it collapses entirely in situations that are common in the Canadian Rockies. We sell these packs in Canmore and we'd rather you bought one understanding exactly what it does. This guide covers the evidence, the limits, and the single biggest reason airbags fail.
Key takeaways
The largest study of real avalanche accidents found inflated airbags cut mortality from 22% to 11%, an absolute reduction of 11 percentage points, or roughly half the risk.
Airbags work by preventing deep burial, not by protecting you during the slide. Adjusted risk of critical burial drops from 47% to 20% when the bag inflates.
One in five airbags in that study did not inflate. Sixty percent of those failures came down to the user not deploying the pack, not to mechanical fault.
An airbag does nothing for trauma from trees and rocks, nothing for terrain traps, and nothing to help anyone locate you once you're buried.
Airbag packs at Vertical Addiction run $749 to $1,999 CAD. Cartridge systems occupy the lower half, electric systems the upper, and electric packs cost nothing to reset, which is why people actually practice with them.
Do avalanche airbags work?
Yes. The largest study of real avalanche accidents found that victims wearing an inflated airbag died 11% of the time, compared with 22% for those without. That is an absolute reduction of 11 percentage points. The benefit is real, smaller than earlier estimates suggested, and entirely dependent on the bag actually inflating.
That figure comes from a 2014 study published in the medical journal Resuscitation, led by Pascal Haegeli of Simon Fraser University. His team analysed 245 avalanche accidents between 1994 and 2012 across Canada, the United States, Austria, France, Norway, Slovakia and Switzerland, adjusting for avalanche size, injuries and burial depth. It remains the reference point for this question, and it's worth knowing as a Canadian skier that the researcher behind it is based in British Columbia. Canadian accidents are in the dataset.
Read that mortality number carefully. It does not mean 89% of people in serious avalanches survive because of an airbag. It means that among people caught in avalanches large enough to bury or kill them, the death rate roughly halved. Most people caught in avalanches survive with or without one. The airbag moves the odds in the cases that go badly.
How does an avalanche airbag work?
Pulling the handle inflates a balloon of roughly 150 litres. Moving avalanche debris sorts itself by size, pushing larger objects toward the surface, the same reason the big nuts end up on top of the jar. The inflated bag makes you a larger object, so you're more likely to finish on or near the surface instead of underneath it.
This matters because of what actually kills people in avalanches. Asphyxia is the leading cause of death, and burial depth is the strongest single predictor of survival. An airbag doesn't protect you during the slide. It changes where you end up when the snow stops.
The study puts numbers on that mechanism. Adjusted risk of critical burial, meaning your head finishes under the snow, was 47% for people whose airbags didn't inflate and 20% for people whose did. Once someone is critically buried, adjusted mortality is 44%. For those not critically buried, it drops to 3%. That gap between 44% and 3% is the entire argument for wearing one.

Where an avalanche airbag will not help you
An airbag solves exactly one problem, burial, and does nothing about the others. In Rockies terrain, where a lot of touring happens in and above trees and over terrain traps, those others come up often enough to matter.
Trauma. An inflated balloon offers no impact protection. Carried into trees, over rock bands or off a cliff, the airbag is irrelevant. This is not a minor caveat in the Bow Valley, where treed touring is the norm.
Terrain traps. Gullies, creek beds and flat benches below a slope create deep deposition zones. Enough snow piles up that flotation stops mattering.
Getting found. If you're buried, the airbag contributes nothing to the search. Your partners find you with a transceiver, a probe and a shovel, or they don't find you in time.
Decision-making. There's a real concern among guides and researchers that wearing an airbag nudges people into terrain they'd otherwise avoid. No safety device survives that trade.
Why do one in five airbags fail to inflate?
Across the 245 accidents studied, 20% of airbags did not inflate. Sixty percent of those failures were attributed to deployment failure by the user, not to mechanical fault. People didn't pull the handle, or couldn't reach it.
That finding reframes the purchase. The pack isn't the safety device on its own. The pack plus a person who has rehearsed pulling the handle is the safety device. The most common mistake we see at the counter is a customer who has owned an airbag for two seasons and has never once deployed it, often because it's a cartridge system and a practice pull costs money to reset.
Deploy it at least once before the season starts, wearing the layers you actually ski in.
Check handle position every time you put the pack on. A jacket, chest strap or camera harness will bury it.
Do the leg strap up. An unsecured pack can be torn off you in a slide.
Favour a system you'll actually practice with. This is the strongest practical argument for electric: with no cartridge to refill, rehearsing is free.
What does an avalanche airbag cost in Canada?
Airbag packs at Vertical Addiction run $749 to $1,999 CAD. Cartridge systems sit in the lower half of that range and electric systems in the upper. The purchase price isn't the whole picture, because cartridge packs carry a reset cost every time the bag goes off.

Run the maths over a few seasons before you decide. A BCA Float 42 2.0 at $749, plus a spare cylinder at $249.99 so an empty cartridge never grounds you mid-season, plus $40 per refill, sits a little over $1,000 after a couple of deployments. The Ortovox Litric Zero 27 starts at $1,750 and covers unlimited deployments for the price of a recharge.
So electric genuinely costs more, and what the extra buys is the freedom to practice. Given that the single most common reason airbags fail is that nobody pulled the handle, that freedom is worth more than it looks on the shelf. If budget is the deciding factor, a cartridge pack you actually carry beats an electric pack you can't afford. Just budget a refill a year and use it.
Frequently asked questions about avalanche airbags
Are avalanche airbags worth it?
If you already carry and know how to use a transceiver, probe and shovel, and you regularly travel in avalanche terrain, yes. Halving your mortality risk in a serious slide is a meaningful return on $750 to $2,000. If any of those basics are missing, that money buys more safety spent on training and a rescue kit first. An airbag is the fourth item, not the first.
What kills most avalanche victims?
Asphyxia, caused by burial. That's why burial depth is the strongest predictor of survival, and why a device that reduces burial depth reduces deaths. Trauma is the second cause, and airbags do nothing to address it.
Does an avalanche airbag replace a beacon, probe and shovel?
No, and no avalanche organisation suggests otherwise. An airbag reduces the chance of burial. The rescue kit is what saves you once you're buried. They solve different problems, and the rescue kit solves the one with a clock on it.
Can I fly with an avalanche airbag?
Usually, with conditions that differ by airline and by system. Cartridges normally have to be empty and declared, and battery or capacitor rules apply to electric packs. Check with your carrier well before you travel. Showing up with a full cartridge is how packs get confiscated at check-in.
How often should I deploy my airbag for practice?
At least once before each season, and once when the pack is new. Electric systems make this painless since a reset costs nothing. For cartridge systems, budget for one refill a year and treat it as part of the cost of ownership rather than an optional extra.
Where to start
Buy the airbag if you already carry a transceiver, probe and shovel, already know how to use them, and already read the avalanche forecast. At that point it's a genuine improvement to your margins. If any of those three are missing, spend the money there first. Avalanche Canada's forecasts and an AST course will do more for your odds than any piece of equipment, and every researcher who has studied this says the same thing.
If you're in Canmore, come in. We'll fit the pack loaded, show you where the handle sits with your jacket on, and let you pull it. That last part is the one most people skip, and it's the one the data says matters most.
