Black Diamond AvaLung II
The 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.
This product can only be shipped to U.S. addresses.

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 Black Diamond AvaLung II is a simple sling that acts as a life preserver for your lungs if you're trapped in an avalanche.
Extends your air supply from the typical 15 minutes after burial to 58 minutes.
Average rescue time with beacons is 20 minutes, so the AvaLung is well worth its small 9 ounce package.
AvaLung mouthpiece delivers fresh air directly from the snowpack through its bi-valve intake box, and expels carbon dioxide to the exhaust port.
Mouthpiece must be inserted before avalanche debris restricts movement.
Minimizes 'ice masking' and tracheal packing to maintain an open airway.
Worn over your clothing, the lightweight sling can be used in all-weather conditions.
Also available as an AvaLung pack; we stock the Black Diamond Anarchist AvaLung, Outlaw AvaLung and Covert AvaLung.
The innovative Black Diamond AvaLung is perhaps the most important piece of life-saving equipment you can wear in avalanche terrain.


The AvaLung II by Black Diamond weighs less than a pound, offers better breathing performance than your own lungs while under snow and wears easily over your existing outerwear.

The Black Diamond AvaLung II is a must for anyone in the backcountry. The design of this product is genius. Pulling oxygen from your environment and discharging your CO2 will save your life in an avalanche. When you're buried under the snow and waiting for your buddy to get his beacon, shovel, and probe out, time is crucial. Without the Avalung you may only have a few minutes to live. SO I hope your friend is quite a good digger. But with the Avalung and an extra 30-45 minutes of oxygen flow you have a much higher chance of surviving after being buried. Check out my attached picture to really understand the risks.
I use the Avalung with my North Face ABS Vest. Fits perfectly. The mesh part of the vest lines up with the vent for the Avalung to discharge CO2. I've yet had to use it, thankfully. However, I breathe much easier knowing I have the Avalung on me.
If you live in an area with wet snow, you should really really buy this. The wet snow makes it harder to breathe regularly under the weight of snow. And this will really help.
Remember, asphyxiation is not fun. Buy an Avalung.

I got my hands on an Avalung last season and I wore it every day I was in the backcountry and on high avi days in bounds. Its a super small piece of equipment that I hope I never have to use, but if I do its nice to know it is there. I am 5'8" 150 lbs female and lets just say... nature was very generous to me in the chest and I wear a small/med which fits perfect even over some of my baggier ensembles.
I never use the Lung to justify any lines I may choose, its just a piece of gear that is there if I have made a mistake and all else fails.
Make sure you are skiing with it in your mouth cause it wont help if you aren't able to get to the hose once buried.

I love having this thing. It can feel like you are super strapped up when you have your beacon then this then a pack, but you get used to it. One thing is you have to drill yourself to get that mouthpiece in your mouth. I try to think about it at the top and make sure the tube is in a good position. Then if I crash, as soon as I can I try to get the tube in my mouth just for good practice. Another thing to be careful of is feeling invincible. I had a buddy who had one before me who would always say "I'll go first because I have my avaluang." Which is a bad way to think. Airbag, or avalung. It should never effect your decision making.

I got one of these for Christmas and have been lucky enough to use it a few times on deep pow days. No avalanches for me but skiing the deep blower pow, this helps a lot and keeps you from having to stop to come up for air! Part of me wishes I would have spent the extra 40 dollars and got the avalung backpack, but overall I am happy with how this fits and it's ease of use.

Alexa Shaw at on 01/30/2013

Don't leave home without it.
I'm about to start my second season with the Avalung. Thank goodness I haven't had to deploy it yet, but it's nice to know it's there.
At 5'10" with a 41" chest, M/L fits me like a charm and doesn't interfere with pack straps. I like having the standalone Avalung because I can use it with any pack or by itself.
If you spend time in the backcountry, get one of these.

Dave Marcus at on 10/29/2012

Brilliant idea and not too expensive. On the other hand, it's not easy to ski with it in your mouth due to 1) airflow resistance 2) tension from the tubing.
Also, mouthpiece feels like it's about 20-30 degrees rotated off axis from my mouth.
I will continue to ski with it (why wouldn't you?), but certainly has room for improvement.

Brian at on 02/01/2013

Haven't had to use it and hope I never will, but I'm sure it would help me if I do. Sturdy make, easy to wear with other gear and adjust. Breathing through is slightly difficult, but its not meant to replace your mouth.

Just purchased the Black Diamond Avalung II and am stoked. Fits great over a 2XL North Face coat, and my XL Volcom jacket. Its so light, I hardly realize it is there.

Robert Mrdutt at on 02/05/2013

Excellent product. I only wish I could get this integrated with some of the ABS solutions out there. But until then I'll continue to rock both. Thank you!

Don't be afraid to be afraid. Always use all the safety gear you can get your hands on.

I had an Avalung pack for 3-4 winters, but I know have an ABS pack & feel it is best for me. I was caught in a slide a couple years ago & could not get the tube in to my mouth was when I was cartwheeling multiple times. I feel safer with this ABS pack I have, plus I do know a couple guys who have had to pull their ABS cord over the last couple winters.

Todd Kehoe at on 07/24/2013

Thankfully there have been no avalanches for me but skiing the deep blower pow, this can keep you from having to stop to come up for air!
In hindsight would have spent the extra money and gone with the avalung backpack. This avalung fits good enough around your chest, but it is still annoying to ski with something strapped to your chest. The avalung backpacks look more comfortable while still having easy acess to the actual avalung.

Carver Shaw at on 09/23/2013

If you are a female with any sort of bust get the M/L. I thought S/M would be fine. And M/L was for large males?.very wrong. To have room for your beacon, bag, bust, and avalung?.you need the M/L. It was designed for a male and crosses right over?.a very uncomfortable spot. Get the larger version for more strap length to finagle the avalung to fit comfortably.
