Ski Packs

Here is a great technology for avalanche victims. It's a backpack with an ava lung built into it. An ava lung is a tube that transmits your exhaust behind you so you don't build up an icy layer around your face keeping the all important oxygen out.
Narrowed it down to these two packs found at REI.
