AvaLung II™ is a remarkable filtration device that draws air directly from the snowpack, allowing you to breathe if trapped in an avalanche.

  • Features

    • Increases the surface area from which you breathe; air is pulled in by a mouthpiece attached directly to the apparatus
    • Exhaled carbon dioxide is directed out the exhaust tube to ensure fresh air supply and to prevent an ice layer which could seal off the oxygen supply
    • AvaLung II has repeatedly been shown to provide an air supply to buried test victims
    • Worn over your clothing, the lightweight sling does not impede breathability or add warmth, so it can be used in all weather conditions
    • User must be able to get the mouthpiece inserted before avalanche debris restricts movement; snowpack or injury can prevent its use
    • As with avalanche beacons, AvaLung II is not a substitute for wise assessment of hazardous avalanche terrain


    Size Small/Medium is for those weighing from 100 to 160 lbs. and size Medium/Large is for those from 150 to 225 lbs.
