Black Diamond AvaLung II

The Black Diamond AvaLung II is a simple sling that acts as a life preserver for your lungs if you're trapped in an avalanche. Extends your air supply from the typical 15 minutes after burial to 58 minutes. Average rescue time with beacons is 20 minutes, so the AvaLung is well worth its small 9 ounce package. AvaLung mouthpiece delivers fresh air directly from the snowpack through its bi-valve intake box, and expels carbon dioxide to the exhaust port. Mouthpiece must be inserted before avalanche debris restricts movement. Minimizes 'ice masking' and tracheal packing to maintain an open airway. Worn over your clothing, the lightweight sling can be used in all-weather conditions. Also available as an AvaLung pack; we stock the Black Diamond Anarchist AvaLung, Outlaw AvaLung and Covert AvaLung. The innovative Black Diamond AvaLung is perhaps the most important piece of life-saving equipment you can wear in avalanche terrain.
