In the world of ski touring and freeride skiing, safety is never a matter of chance. The avalanche airbag backpack has become an essential piece of avalanche safety equipment for anyone venturing into avalanche-prone terrain. But with so many models, inflation systems, capacities, weights, and brands offering different technologies, it’s not always easy to know how to choose the right avalanche airbag pack.
This comprehensive guide aims to help you make an informed choice, based on a clear understanding of how the system works, the technical criteria, and the specific requirements of your chosen discipline.
Key points
- An avalanche airbag significantly increases survival chances in the event of partial burial during an avalanche.
- There are two main types: gas cartridge systems and electric systems.
- Volume (capacity) generally ranges from 10 to 40 litres, depending on the length of your outing and your discipline (freeride, ski touring, mountaineering).
- Leading brands such as ARVA, ABS, Mammut and Ortovox offer high-performance solutions compatible with various accessories.
- Weight, handling, balloon placement, pockets and ergonomic shoulder straps are key factors for optimum comfort.
- The best avalanche airbag pack depends on your skill level, frequency of use, chosen system and budget.
Avalanche airbag backpack: principle and operation
The avalanche airbag backpack is first and foremost a safety device designed to increase survival chances in an avalanche. Its principle is based on inverse buoyancy: when triggered, a specially shaped airbag inflates instantly to keep you near the surface of the moving snowpack.
General operation
- A trigger handle (usually located on the left shoulder strap) activates the system.
- The airbag inflates either via a compressed gas cartridge or a lithium-polymer battery powering an electric fan.
- The balloon reaches full inflation in 2 to 4 seconds, providing enough float to prevent complete burial.
- After use, the pack can easily be repacked and rearmed.
The crucial role of the avalanche airbag
The goal isn’t to avoid an avalanche, but to reduce its consequences. In most burial cases, a properly deployed airbag keeps the skier on the surface, making rescue easier and greatly improving survival chances.
