Avalanche Airbag Backpacks: How They Work and Why You Need One

What Is an Avalanche Airbag and How Does It Work?

An avalanche airbag is a built-in airbag system housed within a backpack designed to deploy and inflate when the user is caught in an avalanche. The goal? To help the person stay closer to the surface of the avalanche, reducing the likelihood of avalanche burial.

There are two primary mechanisms used to inflate the airbag: one is a compressed air canister, and the other is a battery-powered jet force or fan to inflate the airbag. Once activated, the airbag inflates quickly, increasing your volume and making you more visible.

Types of Avalanche Airbags

There are a few types of avalanche airbag systems to choose from:

• Canister airbag: Uses compressed air or gas; reliable but not reusable without recharging.

• Jetforce airbag: Uses a fan to inflate the airbag and is rechargeable via battery.

• Removable airbag systems: Can be transferred between packs.

• Dual airbag system: Offers redundancy in case one side fails.

Each has benefits, and choosing the right avalanche airbag depends on your terrain, travel style, and personal preference.

How Do Avalanche Airbags Increase Survival Chances?

When an avalanche occurs, a deployed airbag increases your chances of survival by helping you float toward the surface of the avalanche. This works due to a phenomenon known as “inverse segregation,” where larger objects rise above smaller ones during movement.

Studies show that avalanche victims wearing airbag systems have a significantly reduced avalanche fatality rate. However, no system is 100% effective—these are a complement to your avalanche safety equipment, not a replacement.

Key Features to Look for in an Avalanche Airbag System

When shopping for the best avalanche airbag, keep these features in mind:

• Airbag System 3.0: The latest tech, lighter and more reliable.

• Removable Airbag System: Let’s you switch the airbag between different backpacks.

• Dual Airbag System: Offers redundancy and better protection.

• Carry System: Ergonomic support and load balance.

• Protection Airbag: Designed to shield your head, neck, and upper body.

The airbag system on the market today is packed with innovative airbag designs that focus on both comfort and safety.

Are All Avalanche Airbags the Same Size?

Not quite. The size of an avalanche pack often refers to its storage volume, but the airbag inside also varies in volume and shape. A large airbag provides more flotation but adds weight.

Some new models offer a twinbag system for inflation redundancy, ensuring functionality even if one side fails. The airbag system on the market today has come a long way since the first airbag system.

Can I Travel with an Avalanche Airbag Pack?

Yes, but air travel with an avalanche airbag pack can be tricky. Most airlines have specific rules regarding compressed air canisters. Battery-powered systems like JetForce are generally more travel-friendly.

Always check your airline’s policy ahead of time to avoid issues. If you travel frequently, consider choosing an airbag backpack designed with air travel in mind.

How Do You Maintain an Avalanche Airbag System?

To keep your system ready, inspect your airbag and handle for signs of wear. Practice deploying the airbag at home (in a controlled environment) so you’re confident in the field.

Be sure to check:

• The airbag mechanism and electronics

• Zippers and seams so the pack doesn’t get torn

• That the airbag within the backpack is intact

What Should You Know About Using an Airbag in Real Conditions?

Using an airbag isn’t foolproof. Wearing an avalanche airbag requires knowing how and when to deploy it. You must recognize avalanche danger, have the proper carry system, and be ready to act fast.

Combining an airbag with an avalanche transceiver, avalanche beacon, and shovel completes your comprehensive avalanche equipment setup.

What Happens After an Avalanche Airbag Is Deployed?

Once you deploy the airbag, the inflated airbag should help you remain on top. But survival still depends on a fast avalanche rescue response and your companions’ preparedness.

Time is critical. After the airbag is inflated, locating and digging out victims within 15 minutes offers the highest chance of survival.

Are There Any Downsides to Avalanche Airbags?

They’re not light. Even the lightest airbag packs add weight. The market for airbag packs is growing with more streamlined options, but any avalanche backpack will be bulkier than a standard backpack.

Also, they’re not cheap. But for serious backcountry adventurers, they are a worthwhile investment in avalanche safety.

Final Thoughts

Exploring avalanche terrain comes with serious risks, but the right gear, like an avalanche airbag backpack, can greatly increase your chances of survival. While no system guarantees safety, combining an airbag pack with proper training and avalanche safety equipment gives you the best shot at staying safe when the unexpected happens.

While no equipment can eliminate avalanche risk, combining your airbag pack with proper avalanche training, real-time snowpack assessments, and rescue gear like beacons and probes gives you a solid safety foundation. So choose wisely, practice regularly, and never underestimate the power of being prepared.
