Best purchase I made all year. Lots of space for when I'll need this summer on the JMT, but plenty of compression straps to make it just right for a weekend outing. Perfect fit and nice distribution of weight due to AG technology.

Edit:
If I could change one thing, it would be the zippers on the hip belt and the two on the outer back pockets.  The zippers are curved making them impossible to open and close without using two hands (which is important when your other hand is usually busy holding trekking poles!)

Furthermore, I would have save the money and the weight and go for a 50L bag instead.  With so much UL and low volume gear on the market, it is unnecessary to have that much space. (even on a thru-hike!) Fortunately, the "brain" of the bag is removable.  I have taken it off, with no intent on putting it back on.

That being said, because of it's life-time warranty, I'm practically married to the pack.  And I'm not grieving over that.  It's got a fantastic construction, and distributes weight like magic and can be highly customized.  A 30 lb pack feels weightless.
