I've got one but I'm looking to replace it with the upcoming myog thingie. The thing I don't like about it, while also liking it, is the ventilated back mesh. Overall, the pack is a mesh monster. I'm not a extreme cragaholic, just an ordinary guy, involved in scouting. I just don't like how I need to baby it when I put it down, plus the mesh is bad in winter..
So for my part, I wouldn't buy it again, would probably go cottage/myog. On the other hand, I don't have any bad facts about it. It rides very well, I'm 1.74 m tall, 72 kg. I think the volume is very good, especially if you need to easy someone elses burden. Obviously, you can overload it as it's still a lightweight pack construction.
My mixed opinion. :)
