I want to start out with I cannot say enough good about this pack. I used to carry a traditional Kelty Pack and it was fine, but it was a top load. It was such a nightmare when I needed something from the bottom. The 5.11 clam-shells open, nothing is ever lost in that pack. I keep lights in one of the side pockets, tools in the other, fire items in the top, food and gear the in the main compartment, accompaniments in the back. I can attach stuff to it, its rugged and tough. Runs a little pricey, its only downfall, I think around $175, still not bad for a pack. For a weekend or a little more, nothing touches it.
