Avalanche airbag packs

Avalanche airbag packs are safety devices designed to help skiers and snowboarders stay on the surface during an avalanche. They consist of a backpack with mounted canisters that, when activated, rapidly inflate a large, lightweight airbag. This increases the wearer's volume and helps prevent them from being buried or trapped under snow by keeping them buoyant and closer to the surface. The activation is typically triggered manually by pulling a handle. Avalanche airbags have been shown to reduce burial risk and improve survival odds in avalanche situations, making them a valuable safety tool for backcountry winter sports.
