I bought this backpack as part of our 72-hour emergency kit. The large capacity is perfect for storing a lot of essentials like water, food, radio, batteries, flashlights, and personal toiletries. I like the smaller pockets, as I can sort small items into them and not worry about losing them amongst the larger items in the main compartment. I haven't tried carrying it around much, though, so I can't comment on its comfort.
