This is by far the most comfortable backpack I have ever owned. I've done several backpacking trips with several different bags, and I have never had one that didn't give me sore spots or bother in some way. I cannot speak highly enough of how much I enjoyed using this bag. The pocket configuration is great. I love the various compartments and zipper setup allowing easy access to the bottom of the bag. The little pocket on the belt is an added bonus for chapstick, flashlight, pocketknife, etc.
