Avalung 2

The AvaLung 2 from Black Diamond may be the most important piece of life-saving equipment you can wear when traveling in avalanche terrain. It allows you to breathe fresh air directly from the snowpack, then diverts the exhausted air away from your fresh-air intake zone, considerably extending the time your partners have to conduct a successful recovery. f09 avy
