Black Diamond's nine-ounce Avalung II shoulder sling may be the most important piece of life-saving equipment you can wear when traveling in avalanche terrain.
The AvaLung 2 is a simple filtration system contained in a lightweight harness that may allow a person buried in the snow to extract air directly from the snowpack. It functions as an artificial air pocket through which air is taken directly from the surrounding snow pack. The air is directed to the user's mouthpiece via respiratory tubing. The exhaled air is redirected to a different part of the snowpack to minimize CO2 contamination and moisture buildup leading to icing.
Black Diamond AvaLung IIThe Black Diamond AvaLung II is the ideal insurance to survive an unexpected avalanche. This innovative product is designed to let an avalanche victim breathe fresh air directly from the snowpack. It deflects CO2 away from the fresh-air intake so you can have more oxygen and be able to withstand for a longer time. This AvaLung has an ultra-light design and only weights 9.3 oz. so you can take it with you on all your mountain trekking. It comes in various sizes, from small to large for you to choose the one that fits you best. The AvaLung may be the most important gear that you have in the event of accidents. The Black Diamond AvaLung II is a must-have addition to your climbing and hiking gear.
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.
