Best Avalanche Airbags

last updated Aug 04, 2019

Oh, did you think that airbags were confined to just being used in your car in the instance of an accident? Guess what, they have more uses than that. For those of you who love winter activities, such as snowboarding, skiing or ice climbing, you need to be prepared in the instance of a disaster. Trapped by nothing but glistening snow, this can only refer to an avalanche. When you get caught in an avalanche, larger objects will naturally rise to the top while smaller objects will sink to the bottom. With an airbag, your life may be spared. The entire purpose of avalanche airbags is to provide you with a safety measure against an avalanche. While there are other design features that make them great, it all comes back to safety.

Versatile

Well-tested and praised

With a 95% success rate, this is a backpack to consider. It has a slim and narrow design that provides stability and great weight distribution. It uses compressed nitrogen gas to deploy the airbag. The gas, airbag, and handle can all be removed, allowing you to use this backpack for many other adventures.

Read more

Use
The Patrol from North Face uses compressed nitrogen gas. There are two airbags, one on each side of the backpack. They are easily and quickly deployed by pulling down on the ceramic handle on the left shoulder strap. One of the great things about nitrogen airbags is that you can practice at home and then have the canister refilled. It should be noted that the canister is not included.

Features
This is a very durable bag. Not only can it be used for avalanche safety, but it can also be used a regular backpack. You can remove the airbag system and handle and replace it with a hydration pack. There are also attachments for skis or a snowboard. There are plenty of pockets and organizational areas for your gear and tools. Additionally, the hip belt has dual zippered pockets.

Read more

Use
This bag can be used with or without the airbag. The recommended airbag system is the Mammut Removable Airbag System 3.0.

The compressed gas is dependable and not affected by the weather. It has a T-shaped deployment handle which can be adjusted to your comfort.

Features
Accessible is a great way to describe this bag. There are great pockets that provide easy access to the things you need.

Pros:

Features puncture-resistant material easy to repack

Cons:

Could have been larger capacity options available

Black Diamond integrates jet-fan inflation for their Halo 28 Airbag and that is certainly what is most notable here. Not only does this provide exceptional inflation power, but it also does so in the blink of an eye.

Read more

Use
Yes, jet-flan inflation technology is integrated here and it is fabulous. Besides the fact that it will inflate within four seconds, it will deflate after three minutes to create an air pocket. Plus, the system also performs a self-diagnosis on every start-up to conclude if there are any issues.

Features
Even while your skis are attached to this bag, the system will still deploy when needed. In addition, it is also easily repackable and provides zero-cost user practice and friendly performance. Black Diamond provides you with a few color and size options. For colors, select between either black or fire red. Sizes, on the other hand, consist of either small/medium (26-liters) or medium/large (28-liters).

Comfort
The zippered back panel access system and reACTIV suspension system with SwingArm shoulder straps should deliver enough comfort for everyone.

Portability
Past the main compartment, which when totaled with everything else will hold either 26-liters or 28-liters of equipment (depending on the size you pick), there is an internal pocket, a hip-belt stash pocket, and an avy-tools pocket. Some may feel this does not offer enough capacity and that is fine, but do not overlook the other design features that make it spectacular. Features such as the number of separate storage compartments, safety, and inflation technology.

Cons:

Not many features

If you're looking for lightweight, look no further than the Mammut Light Removable 3.0. It's sized appropriately for most day tours and is the lightest airbag pack in the 30-liter volume range. You don't have to spend a ton to save a pound or more vs typical balloon pack models.

Read more

Use
Innovation is key here as Mammut has implemented a design to minimize the chance that your breathing is obscured when the airbag inflates and opens. The airbag opens in a horseshoe-esque manner to concentrate the floatation behind and above your head so you are facing above the snow.

Features
To ensure that the pack does not escape from your grasp, there are included leg loops for security. This pack doesn't have a ton in extra features, but it has a zippered pocket on the side of the waist belt and a fixed gear loop on the other. There is also a small zippered pocket on the top of the pack to help keep small items from getting lost. It is also hydration system compatible.

Comfort
Even with this pack loaded to the brim, you are still promised a comfortable ride. The pack fits a lot of people, from 5'4" to 6'2".

Portability
While you can’t pick from any other color option (just black), you can select a 35-liter or 45-liter model. The Mammut Light Removable Airbag is a unique pack that will work for most backcountry skiers. It's lightweight, with a simple design, that can still hold plenty of your gear.

Pros:

It is water-resistant with the seams taped

Design is glove-friendly

Cons:

Compartment for the ice tools could be built tougher

If you have followed the brand, anytime you see an Arcteryx product, then it will not be a surprise if it features some sort of weather protection. Besides this, they actually implement a battery design for their inflation.

Read more

Use
Safety is at the forefront here with a plethora of design features. This includes an impeller that is custom-engineered to increase the pressure for superior inflation, a single-leg safety loop that is connected with a carabiner and enough air to inflate even when minor abrasions are present.

Features
With a durable and seam-taped design, this airbag is highly water-resistant. In addition, the pack can secure a single ice tool and features compressions straps for skis and snowboards. Past the dual main compartments, also integrated is an internal security pocket and an internal waterproof sleeve. All this considered, you can expect to hold up to 30 liters of gear and accessories. The 30-liter capacity is the only size option, but you can select between two different colors (either black or cayenne).

Comfort
When you see something from Arcteryx, you can expect only the best in craftsmanship and design. Their Voltair airbag is certainly no different and while it is not the cheapest version in the world, good luck finding any better. The padded shoulder straps make this bag easy and comfortable for all-day trekking.

Portability
While the adjustable sternum strap allows you to get the best fit possible, the compressions straps will help stabilize the pack when you are carrying skis or snowboards.

Pros:

Utilizes a jet-fan inflation system to provide air

Repacking the airbag is incredibly simple

Rechargeable system allows you to always practice

Cons:

Putting the clips back when they unravel is annoying

Black Diamond makes another appearance on this list and their Saga 40 and Halo 28 are closer in practice than 100 to 101. Honestly, you could flip a coin to decide and both would satisfy your needs. But, the Saga 40, in specific, does have minor blimps that slightly hurt its overall rating.

Read more

Use
Just as the others, the safety of the Saga 40 all stems in its airbag. If you are really concerned, you can practice deploying this airbag as often as you like. The inflation is powered by a rechargeable battery, meaning that you can charge it when it gets low.

Features
All sorts of compartments are integrated here including an avalanche tools pocket, hip-belt stash pocket, and a zippered top accessory pocket. But, all in all, expect to hold either 38 or 40-liters of gear (depending on the size you choose). You can select from either black or fire red (for colors) and small/medium (38-liters) or medium/large (40-liters).

Comfort
As with their other airbag, Black Diamond designed this pack with a reACTIV suspension system with SwingArm shoulder straps. Plus, they also included zippered back panel access.

Portability
If need be, you can easily transport this pack onto an airport with no restrictions. In addition, the design allows the airbag to be deployed even while skis or snowboards are attached.

Criteria Used for Evaluation

Use

If avalanche airbags are not integrated with the utmost safety in mind and do not perform what they should, then they turn into an overpriced backpack. Anyway, one of the key design elements to take note of is the way the airbag is activated. Typically, this will either be by compression air or a battery or jet-fan.

Even though both are great, those with batteries or jet-fans do hold the advantage in terms of inflation. Here is why. With compressed air, you must get the cylinders refilled with air every time you use it. Not only this but you must do so at certified locations. With a battery-operated airbag, you can simply recharge the battery and are good to go. Again, both work fantastically but one is clearly more convenient. But, there are also other safety features to keep an eye out for. Features such as the system performing a self-diagnosis to see if there are any issues, inflating air in even when abrasions are present and even a locking clasp to prevent accidental activation.

Features

To be honest, these types of features are not necessary but they are ones to keep an eye out for. After all, anything that offers convenience to you is positive. The question is, what is deciphered as a convenient feature? Well, as stupid and obvious as this is going to sound, any feature could classify. In reality, this entire guide could have been dedicated to it. This section is more for those features that are terrific but do not have a specific section they fall into with other airbags.

This could include the inclusion of leg loops for security. When an avalanche hits, the worst thing that could happen is for you to lose your pack. Also, how about water-resistance? You do not see it very often, but some designers will integrate water-resistant technology. Or, this could be as simple as having the option to choose which side the trigger mount goes on. Do you feel more comfortable activating the trigger with your left or right hand? Those that give you the option may appeal to you more.

Comfort

Safety and convenience are both great, but it can be argued that comfort is just as important (or even more). On long journeys, your back and legs will be aching so it is helpful when you have a pack that is not exaggerating the pain. Of all the specific comfort implementations to look for, perhaps the most important is adjustability. With packs, it is nice when you are given the option to adjust the shoulder straps and waist belt (if one is there). At times, you may want it tighter to fit snug to your body. However, this can grow tiresome and you may want the option to loosen it up. With avalanche airbags that offer a stable fit, it can quickly become a hindrance.

However, it does not stop there as padding and stabilization are also important. Padding is self-explanatory, as straps can get uncomfortable on your shoulders after too long. But, features such as a thermo-molded back panel and compression straps will assist in the overall fit and stabilization of the weight.

Portability

There is a high likelihood that when you are off on your adventure, you will need to bring along gear and accessories for the trip. Why bring along another bag when most airbags provide you with enough storage space? That is if you choose the right one. It is important to analyze the different sections of storage that are designed into an airbag. For example, are there pockets on the outside for valuables, pockets on the hip belt, or interior compartments for accessories?

But, probably more importantly, what do you intend on using your avalanche airbag for? Is it for weekend trips or all-day adventures? This is an extremely important question as it will decide the capacity that you aim for. Speaking in a general sense, a pack that holds 20 to 35-liters of volume will work best as a daypack. Beyond this, packs from 40-liters to 50-liters will adapt for weekend trips.

Be Prepared

When you are skiing, snowboarding, or partaking in an adventure that revolves around a giant mountain of snow, you must be prepared for the chance of an avalanche. It may sound crazy, but it can happen to you. While you can’t stop it, you can increase your chances of survival by investing in an avalanche airbag.

Safety

Investing in an avalanche airbag BY NO MEANS that you can or should venture out into more dangerous territory. These bags are designed to help save your life in the event of an avalanche during a normal trek. Do not feel invincible with these bags because you are NOT. Stay safe and take the same safety precautions that you would without the airbag.

In the Midst of the Avalanche

Even though you'll have your avalanche airbag, you should still be knowledgable about how to (try to) survive an avalanche without it. The center of the avalanche is the strongest. When you see or feel it coming, try your best to move to one side of it. Much like swimming, but in frozen water, it's best to try to stay above the snow. If the snow is already coming at you, try to swim in the direction of the fast-moving snow. Once things calm down, you should land a little bit higher and be buried in less snow.

Other Factors to Consider

Style

A lot of times, you will only get one choice when it comes to airbags. At least, this is the case with most on this list. However, that does not mean it is not important as even a slightly different option can make the difference. For example, deciding between a 35-liter (great for a day) and 45-liter (better for weekends) version of the same bag.

Though, color can also play a role. Unlike other types of gear and accessories, manufacturers do not put too much of an emphasis on color scheme and design. But, you will run across those that give you a few different color options. Not hugely important, as it certainly does not overshadow features like safety and comfort, but still something to ponder.

Versatility

While the initial price tag of some of these bags can be a bit shocking, some of them are highly versatile. Some of the designs can be fully disassembled, meaning you can use the backpack without the airbag. If you opt to do this, we only hope that you aren't heading for the snow and that you have an amazing memory and will remember to put the airbag back in. Having the ability to use the backpack for summer hiking trips, travel, and running errands makes the backpack versatile and more valuable. If you are looking for a product that you can use in multiple different scenarios, you'll want to look out for this feature.

Frequently Asked Questions

q: How effective are avalanche airbags?

a:

You know, it seems like a million-to-one chance that you could survive something as detrimental as an avalanche. However, as Dr. Pascal Haegeli (a doctor from the University of British Columbia) tried to prove an avalanche airbag can significantly increase your chances of survival. Dr. Haegeli conducted a study and concluded that those who have an avalanche airbag, in the instance that an avalanche hits, will see their survival rate double as compared to those who do not have it.

Though, it can’t be stressed enough that this is not guaranteed to save your life. While your chances increase, you can still fall victim to the furious disaster. Most of the time, as Haegeli points out, terrain traps such as gullies, cliffs, crevasses, and trees can cause you head trauma. However, having a 50 percent higher likelihood of survival is certainly not too shabby.

q: How do you refill or exchange a compressed air cylinder?

a:

If you choose to forego a battery-operated or jet-fan operated avalanche airbag, then you may have to deal with compressed air cylinders. As stated before, this means that you must get them refilled at certified locations for future uses. But, that is a little vague so let’s further explain the process. Let’s say you are dealing with a BCA (Back Country Access) air cylinder, they have an extensive network of refill locations that are published on their Refill Center Locator web page.

Examples of these locations include fire stations and SCUBA and paintball shops. Also, with BCA, they offer you an exchange program in which you can exchange empty air cylinders for full ones at their location. Basically, you want to ensure that you are near a refill center because if you are not, you may have a hard time finding the means to get compressed air for your cylinder.

q: Will these work in a heavy avalanche?

a:

It may be hard for you to understand at first, but avalanche airbags actually work better when the snow is heavier and thicker. With the way that they work, floating to the surface because they are larger than other objects, the heavier the snow, the greater the density. For math and physics majors, you will then know that this means a lower volume.

While it is not important to fully understand the algorithm that goes with this, take this into example. When the snow is wet and heavy, there is not as much volume that is required from the airbag to float you to the surface. However, when it is light and fluffy, it may require more volume and thus more air. Even though it seems confusing and backward, you are better off getting hit with heavy snow than light.

q: How often should you test an avalanche airbag?

a:

This is the one area of concern for compressed air cylinders. Because you must get them refilled after each use, you may try to save your time and money and forego running a test to ensure there are no issues. However, can you imagine anything worse than having an avalanche approach and having your airbag have malfunctions? In this case, the airbag will do you no good and your chances of survival will be cut in half. But, for battery-operated airbags, you can test them as many times as you please as you can simply recharge the battery.

No matter, though, you should partake in a test run every once in a while. For instance, BCA encourages doing so at least once per year. Given that you should not run into avalanches very often, once should more than suffice. Honestly, there is a high probability you will hardly ever use your airbag but when you need to, it is comforting to know it already worked.

q: Can you fly with an avalanche airbag?

a:

It is important for you to understand that the Transportation Safety Administration (TSA) will not allow air cylinders on commercial airlines. That is, as long as they are filled with air. If you keep them empty, then they will be allowed. If you need to travel via airlines and you want to bring along your compressed air cylinder avalanche airbag, this would be an ideal time to test it as the canister needs to be free from air.

However, the TSA will check inside to ensure that it is empty (and nothing else peculiar is inside). As such, before they even have the chance you could separate the head from the cylinder. From there, you will be good to go. But, more importantly, ensure that a refill center is near your destination. BCA, in specific, aims to do their best to have refill centers near every resort and every city near a ski area.

q: Is it really necessary to use a leg strap?

a:

It is safe to assume that some of you may think it is overkill for a leg strap to be included in an avalanche airbag. Just as some may believe that riding a bike with a helmet is not necessary. But, if you do not have the hip strap pulled tightly on the pack then there is a chance the pack will be pulled over your head when an avalanche hits. However, if you have it attached to your leg then this will be prevented. Of course, if you securely tighten the hip strap then you may not feel the need for a leg strap. Basically, it is an extra precaution and it can also assist in saving your life.
