So I'm pretty picky when it comes to buying things... I ordered this one, the ABS Vario 30, BCA Float 32, and Mammut Pro Protection (with the horseshoe airbag around your head) and the Ortovox came out as my favorite, returned the rest. The biggest reason it won was carrying comfort - the strap materials and the way they distribute the weight are far better. Still not as comfy as the Osprey Kode it's replacing but very nice. It's got plenty of space to carry lots of gear for a full day or more. The variety of pockets is nice for organizing. You can shove a camelbak bladder in the airbag/canister compartment in a bit of a ghetto fashion and have the hose w bite valve in the zippered strap you don't have the airbag pull cord in, this was a slight downside. Carrying a splitboard full assembled on the pack isn't ideal either, it's much easier carried in ski state. Other than those 2 items the pack is great, the ABS Vario 30 which came in 2nd did a much better job at those 2 items but wasn't as comfortable to carry and the cylinder pressed into your back a bit with a full pack. From what I read nitrogen and 2 bags (ABS system) seemed like the way to go over air for reliability even though you can't fly with it.
