To begin, the dual airbag system ensures that if one inflation fails or one bag is damaged by trees, etc. you will still have at least one airbag fully inflated. Additionally, ABS is using new technology with their bag materials which creates a much lighter and much stronger bag. The airbag material is the same material used on zodiac boats which means that it is nearly impossible to shred if punctured. The trigger mechanism is a nearly fail safe pneumatic system that only takes approximately 18 pounds of force over 2 cm's to trigger inflation. Non-pnuematic systems can take up to 45 pounds of pressure over 6 inches in length trigger inflation. From my experience, once you're caught in an avalanche things happens so fast that the easier a trigger is to pull the better.

I also love the fact that the ABS
is constructed of a base system that has the airbag safety system in it,
and the actual backpack is zipped on allowing for different size packs
to be attached. This, I believe, makes buying this pack a worthy
investment because you are able to have different sized packs for
different types of days. 90% of the time I use the Powder 15L, which
fits my shovel, probe, some food, water, an extra pair of gloves, a thin
layer, a few other small things, and my skins (at that point it's
starting to get pretty tight). If I need more gear than this I would use
the Vario 25L (or 40L). Please note that the Powder Line and the Vario
Line are not interchangeable. I prefer the Powder Line because it is a
little less bulky that the Vario system, but it is more limiting with
only having the 5L and 15L as the two sizes. So, if you need that larger 40L the Vario would be the way to go.
These ABS backpacks
are very durable (and I'm talking about the base system). My backpack
went through some heavy forces in the avalanche so ABS did an integrity
check on my pack. The pack was found to be completely intact and in
perfect working condition, so I am still using the same base system.
The
pack includes straps and an exterior helmet holder, so you can dangle
stuff off if need be. The ski carry system is just okay (using the
straps that are included), but it works and the pack is so awesome it is
not the biggest deal to me. The waist buckle is strong and easy to use,
I don't have to take my mittens off to lock and unlock the steel
buckle.
ABS uses a nitrogen cartridge which makes it lighter and
smaller than other brands. While some may scoff at the additional weight
of an avy bag, the ABS pack does not feel heavy, it fits very snug on
the body and I have never felt that my pack has extra weight to it when
it's on my back.
Any kind of avalanche safety backpack is not the
end all be all device that usurps the necessary knowledge to be in the
backcountry, your sound judgement, and the other mandatory backcountry
tools such as a transceiver, shovel, and probe. Rather, these backpacks
are a last ditch effort if you find yourself in an unfortunate situation
of being caught in an avalanche. Accidents can happen and these packs
can help save your life. It saved mine.

Who was it that dug you out?

Interesting story Elyse, glad you made it out OK.
ReplyDeleteAs people head more and more out into avalanche terrain, this kind of pack will save more peoples lives. I'd never really considered one (I've got a BD avalung pack)until I went heli in the Chugach last year. Whilst the avy risk was "low" - when you're looking down at 2,000 feet of 50 degrees vertical it'd be nice to know that "if" it does slide, you've got a high probability last ditch survival chance with one of these.
I'll be buying something along these lines for sure!
