First off this pack is very well designed, and looks even better in person. I definitely like the looks of the 36 over the 30, plus the added room over the 30 liter is great. I really like the added waistbelt pockets to make up for space taken up by the air bag system.
In addition to the great design, the material on this pack is bomber and very durable. The pack has plenty of padding on the back plus a back panel zipper access (mainly for getting to the airbag system, but some gear can be stored there as well), but the padding isn't ventilated, but that's not a deal killer.
Do note that even though is a 36 liter pack, after the airbag system takes its space, you're left with around 20 liters usable room at most. I wish there was a separator for the avy gear pocket from the rest of the storage, but everything is piled into one pocket. And I wish they made the airbag pocket a tad bit bigger and its pretty tight with the airbag in there and getting a deployed airbag back into the pack isnt as easy as other packs. Just a small bit of added space would make this pack a 5 star rating in my books.
The added mesh helmet holder and compression straps are good enough to store your gear for the uphill. This pack will definitely be getting a lot of time from sidecountry runs to full days in the backcountry. Worth the cost of admission.
