Combining the ABS Airbag Pack with the Avalung
I just received what is (to my knowledge) the worlds first and only backpack that incorporates both the ABS airbag and the Black Diamond Avalung.
I call it my Ultimate Mutant Avalanche Pack.
For those who don't know about the ABS airbag pack, there is a description of it here:
http://www.backcountrymagazine.com/n...ves_oct07.html
Here are some pictures of my mutant pack:
Here is how it came about. I got tired of wearing both the Avalung and ABS pack. Too many straps, and I didn't like having to remove the Avalung every time I put on or took off a clothing layer (because the Avalung has to go on the outside.)
So, I called Ron Rob at R2 Packs.
http://www.r2packs.com/
R2 is a truly custom pack maker. They work with you to design and build literally anything you want.
I went to Ron with the idea of combining the avalung pack with the airbag pack.
The task was made somewhat easier by the fact that the ABS airbag pack I have is modular. There is a standard frame, that contains the airbag, and then you can zip on different pack bags of different volumes.
http://www.absairbag.de/vario.php?ch...c237c2f4033364
So, we didn't have to tweak the frame or airbag portion of the pack, we just had to figure out a way to incorporate the Avalung into the pack bag.
Initially, I thought that I could just incorporate my existing Avalung into the pack, but after examining the BD Avalung packs, it became apparent that the pack avalung has some important differences compared with the stand alone avalung. So, I bit the bullet and bought a BD Covert avalung pack.
The Covert pack was canibalized for parts, and the avalung parts were incorporated into the pack bag. The packbag itself was created by R2 from scratch, using lightweight fabrics, and was designed to my specifications, with pockets sized to fit my shovel, probe, and snow saw, in addition to other features like a larger main compartment, hydration pocket, and a floating lid that I could secure a helmet under (unlike the fixed lid on the ABS packbag.)
The final finished product is pretty cool, and is lighter weight than the original ABS pack, even though it is significantly larger in volume.
I'll be skiing with it on Saturday.

You're a bit late, JONG. It's been done. AFAIK the original AvaLung pack idea came about from people modifying their AvaLung 2s to fit to packs, so my idea was hardly original. Mine's since been rebuilt but the idea's the same. FWIW the standalone AvaLung 2 is exactly the same as the internal components of the AvaLung packs, except the packs have longer hoses. I've used components from the old school vest, the standalong AvaLung and the packs.
Where's your mouthpiece? Is that it inside the zip right next to the ABS trigger? Did you try rigging up the pack with trigger and mouthpiece together - I reckon they might get in each other's way. I've got the AvaLung mouthpiece on the right shoulder strap and the ABS trigger on the left.

p.s. what's the weight and interior volume specs?
p.p.s. how old is your sister?Do you by chance happen to own a large, yellowish, very flat cat?

Hmm. I just thought of something. Would it not be much better to inflate the abs with air rather than co2? I guess the balloons deflate after awhile when buried(?), and I'd rather get some extra air in my pocket down below than some extra co2...

It actually uses N2, not CO2. And it has a venturi value, so it's something like ~3 parts air to 1 part N2. And the bags don't deflate. And the intent is that you don't get completely buried anyway. So all in all there's not much to worry about with respect to your comments.
Various places sell replacements and refills. Google will reveal them. If you're in Europe there are a bunch of shops that will sell canisters if they sell the packs.

Hi Kai,
I am thinking of integrating the stand alone avalung into the ABS vario pack.
You mentioned that
"Initially, I thought that I could just incorporate my existing Avalung into the pack, but after examining the BD Avalung packs, it became apparent that the pack avalung has some important differences compared with the stand alone avalung"...
I am just wondering whether there is anything that could come in the way combining stand alone avalung with vario ABS pack along the steps described in the link below?

Many thanks.

I know the BCA pack does deflate but it is very slow and minimal, I am pretty sure that the ABS pack does not deflate.
To the earlier question about why the ABS does not use air, they chose N2 because it is not affected by altitude or temperature so you always have the same pressure in the tank to inflate the bladders properly.
Not saying that the BCA and Snowpulse which use the same CO2 system are not reliable, it is just what each chose and their reason.

The snowpulse is the only one that deflates at a notable rate, as it wraps around your head this would make sense for this unit to provide you with breathable air.
Btw, nice work, that looks like a great setup.
for those looking to pick up a pack, or needing a swap for the ABS (they've recently gotten MUCH cheaper) check out this guy http://www.snowbigdeal.com/servlet/StoreFront
They're local to CO & UT & may be able to save a decent chunk of $$ on the hazmat shipping if you're around here, but otherwise they sell all 3 brands & have decent prices.

Float 30 in stock... Love the price, but not the design. Skicarry, Iceax for instance?
And why not the swapsystem seen on ABS and snowpulse, sure abit for expensive, but 30L is abit small sometimes.
Made more for sleddnecksm maybe?
All this is just me thinking, someone actually knowing?

Thanks for the link!
We have the The Float 30 in stock, but it does not have any straps for ski-carry or ice-axe. Next year's design will have the additional straps as well as hydration, but unfortunately the price of the Float 30 pack is going up to $699 instead of $499.THE AVALANCHE AIRBAG EXPERTS

Correct. This years BCA pack targets snowmobiles. In there first year of production they just wanted to get something functional to market. Next year, as I understand, they'll have a ski-orientated air bag pack.
And Wannabe. Why would Nitrogen behave any different then Oxygen or Carbon Dioxide due to pressure or temperature changes? All gases behave more or less the same. Google the Ideal Gas Law.

Last year i saw this pack save a friend of mines life up in the todrillo range. If he had not had the pack, the slide would have either broken him in two or killed him. He deployed the back and was never taken under. The debris pile was about 8-10 feet deep.
2 weeks ago, we all used the ABS packs up there. I feel the avalung really does not have much value when compared to the ABS (IMHO). A slide of that size would have crushed him and if he were to have been buried, the avalung would have been useless because of the beating he would have taken.

The canisters for ABS use compressed nitrogen. If you have an empty canister (and used trigger) that is either black or yellow, then we will exchange your canister for $29 (+ Hazmat shipping charges if applicable).
If you don't have a canister to exchange, you can purchase the canisters directly on our website.
