Description
Skiing off piste comes with risk, not least being caught in an avalanche. But safety equipment, like wearing a backpack that incorporates an avalanche airbag has been shown to save lives by preventing burial, so more and more people are wearing them.
In an avalanche, larger objects rise to the surface, while smaller objects sink to the bottom. An airbag system incorporated into a backpack, with a large balloon or balloons that inflates at the pull of a cord, is designed to make the person wearing it larger so that they naturally rise to the surface of the snow.
