Bought one at The Mountain Shop in Portland about 10 days ago and tried it out this last weekend in the Columbia Gorge, so not much experience with it yet, but here is my initial reaction. Regular size shoulder yoke, and medium hipbelt. The shoulder yoke is infinitely adjustable as it attaches to the yoke with velcro. I'm 6'2"+ and I had to extend it above the large about an inch. Not sure how much more adjustment there would be. SMD only has small and regular sized shoulder yokes. The hip belt is substantial and has good adjustment with an upper and lower adjuster on each side. I liked how this worked and was surprised what a difference a small adjustment made. The back main pocket expands to hold a lot and is secure. The side pockets expand well. One complaint is that the tops of the side pockets are easily expandable too with no way to secure larger items. Seems like some items may work there way out. Didn't have any problem but concerned me. The shoulder harness pockets are high up, very small, and I found them to be hard to access, so didn't (and doubt will ever) use them. Lots of rain over the weekend and seemed to be pretty water resistant, but not water proof. Took extra stuff/water to 25-30 lbs as I wanted to test it. Very comfortable, stable (compression straps work very well), and easy to pack, and easily handled all of my gear with enough room for extra water if needed. Last week I put in my daughters Bearikade Weekender. Fits vertically, but not quite horizontally. They are 9" round and 10.5" high.
Overall Seems like a very nice pack
