Black Diamond Avalung II
The AvaLung II allows you to breathe fresh air directly from the snowpack, buying you precious time during an avalanche rescue.
Rebreathing exhaled air when you’re buried causes suffocation because the air becomes oversaturated with carbon dioxide and depleted of oxygen. The AvaLung II diverts the exhausted air away from your fresh-air intake zone, considerably extending the time your partners have to conduct a successful recovery. This 9-ounce shoulder sling is used by guides, avalanche control workers, patrollers and ski mountaineers.
