The Black Diamond AvaLung has been proven to extend lives of buried avalanche victims. The system redirects your exhales away from your mouth so the nearby snow won’t ice up into a suffocating wall. That means more air from the snowpack is available to you in a dire situation. The Element is a removable AvaLung that works with several BD pack lines, including the ultralight Cirque 30 & 35. Help improve your odds of survival with the AvaLung Element.
