Life Bag, an airbag for avalanche designed for winter sport addicts, is triggered by pulling a handle. The 150 liter airbag will then inflate in only 3 seconds.
The « Life Bag » can easily be reused and refilled. Professionals and resellers have the possibility to refill the air cylinder themselves. Training is therefore possible since you simply have to refill the cylinder after trying your Snowpulse airbag.
