Snowpulse is an airbag designed for winter sport enthusiasts at risk for being caught in avalanches.
As you can see from the photo, Snowpulse is a backpack with an airbag inside, which deploys when you get pummeled with snow. It protects your head and thorax against shock (responsible for up to 20% of avalanche-related deaths), and the bright color helps rescuers find you faster; the room the deployed airbag creates around your head also helps rescuers dig you out faster.
Pretty awesome innovation for those who can’t stay off the mountains during avalanche season. Or for those of us who are paranoid as all hell about getting caught in one. I may buy one just to wear in the car.
