Equipped with a camera, snowboarder Tom Oye sat on the snowy slopes of Whistler, Canada, when he was caught by an avalanche. In just a few seconds, the man was carried over several hundred meters. Fortunately, he was able to escape unharmed thanks to his airbag backpack, offered for Christmas, which allowed him to stay on the surface of the snow. A handle system triggers the inflating of large air cushions. They exploit the phenomenon of inverse segregation: during an avalanche, the most voluminous particles rise to the surface, whilst the smallest ones are driven to the bottom. Thanks to the airbags, the volume of the rider is increased, thus minimizing the risk of burial.
