Got a chance to try out the new avalanche safety inflating backpack attachment this past weekend at Diamond... Conditions were pretty sketch, so we figured it'd be good to deploy the device before dropping in. As you can see in the picture it was probably a good thing to have as most of the bowl slid. It was pretty touch and go there for a bit, but I'm fairly confident that she may have saved me from at least an ankle deep burial.
I would be surprised if I didn't see one of these on the backs of a lot of backcountry skiers in the near future.
