This is a good pack, but I did find some things that I didn't like about it. I know several other people put this in their reviews as well, but the first thing I found was don't put too much weight in it or the suspension becomes uncomfortable. The second thing was also what James Jenden mentioned in his review, when you have a lot of gear in your pack you can't fit a camelback bladder. At least not without it breaking and getting your stuff wet. Other than those two things though, I do like the pack. I use it just for overnight camping trips when I don't have to carry too much stuff.
