Black Diamond AvaLung II

• 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
