I've owned this pack for 3 years and used it on around 10 backpacking trips and several hiking trips, as well as taking to to Mexico and Colorado traveling. I've taken it to the top of two mountains and gone climbing and canoeing with it. I recommend it highly to anyone who is a serious ultra-light backpacker and who needs a pack that takes a beating.
My base pack weight is usually around 12 pounds, around with food, water etc. It fits well to the back if you don't pack anything too pokey right against your back. The hip belt is not padded, but I find it comfortable and totally sufficient. The shoulder straps are comfortable if you wear a shirt, but need need some extra padding if you like to take your clothes off in the hot weather.
The bombproof dyneema fabric is great. I treat my gear rough, but it only has two small holes: one melt-hole from a spark, one small laceration from who knows what (I suspect by buddy's crampons). The cuts have been there for several months and haven't gotten any larger.
One downside: the side mesh pockets are not large enough for Nalgene water bottles. I don't use Nalgenes, but I'd prefer them to be larger anyway to fit more easy access stuff.
Also, this backpack is best used mostly full. If you pack only a few energy bars, a water bottle, and a jacket, no matter how tight you cinch the straps it's going to shake around on you.
