The Black Diamond AvaLung II is one of the most important developments in avalanche safety since the avalanche beacon. It should be a part of every backcountry traveler's tools. Use it in conjunction with a shovel, probe, transceiver, and experienced and capable companions to increase your chances of survival should you be caught in an avalanche. The Black Diamond AvaLung is designed for backcountry powder skiing & snowboarding, alpinism, and snowmobiling. The AvaLung is a simple filtration device which draws air directly from the snow pack. Even dense avalanche debris consists of approximately 50% air. The AvaLung membrane increases the surface area from which you breathe, making it possible to pull this air from the snow. You breathe in and out through the tube. The patented system within the AvaLung separates the O2 from the exhaled CO2, which is directed away from the air intake and out the back of the vest to diffuse through the snow pack. At the on snow demo last season, we watched them bury a guy in the snow for over an hour. When they dug him up, he was a little cold but otherwise fine (they even tested the CO2 levels in his blood). While we think that the AvaLung is a great innovation, we recognize that it does have its shortcomings. While tumbling in a slide, you might well lose your bite on the mouthpiece--or you may not even have had a chance to bite it. However, we feel that this device can increase your chances of survival. It's another great tool in your quiver. Get the Avalung II size that corresponds with your T-shirt size. They are highly adjustable.

The Avalung was on the market for less than a year before it saved its first life. Two winters ago, a helicopter ski guide in Valdez, Alaska got caught in an avalanche and was buried alive. He was able to use the Avalung while rescuers searched for him. The extra time he was able survive under the snow while breathing trapped air was credited as one of the factors that saved his life. The prestigious Journal of the American Medical Association (J.A.M.A.) recently printed an article acknowledging the research and methodology used in testing the Avalung, and concluded that the use of the Avalung could reduce the probability of asphyxiation by extending the amount of time someone can survive after being buried by an avalanche. Even more people had their life saved last year by using the Avalung. It is comfortable with or without a pack, and the ultra-minimalist harness design is secure but not restrictive. At 1/3 the cost of an avalanche beacon, weighing less than a pound, it is one of the most important developments since the avalanche beacon. The Avalung II has a built-in filtration device that draws air directly from the snowpack. A one-way valve allows you to breath air trapped in the front body area. The exhaled C02 is exhausted in back of the potential victim. This significantly reduces the probability oficemasking and re-breathing exhaled CO2, two of the most dangerous problems a victim faces. In test cases people have lasted over an hour completely buried in the snow. It can be worn in any conditions over your clothing and weighs only 15 ounces

The Black Diamond AvaLung II may be the most important piece of life-saving equipment you can wear when traveling in avalanche terrain. While a beacon can be a great body locator device, the AvaLung II allows you to breathe fresh air directly from the snowpack, buying you precious time during a 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 nine-ounce shoulder sling is proven to extend lives; it's trusted by guides, avalanche control workers, patrollers and ski mountaineers worldwide.
Features:
- Essential addition to your backcountry and avalanche safety tool kit
- Fits unobtrusively over your existing outerwear and pack
- Proper use buys precious time when buried in an avalanche
- Weighs less than 10 ounces

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