I love this pack! I throw my camera and hiking gear in it and off I go. The fact that it isn't a backpack means that my back doesn't sweat as I hike up and down hillsides. There are lots of pockets and the pockets at the hip make it easy to reach essentials. The fold-out pockets (like for the water bottles) are great - you don't have to use them, but they don't take up space if you decide not to. The one and only gripe that I have is that the knife pocket is smaller than my knife - the knife goes in it, but the flap doesn't close over it.
Pros: Breathable, comfortable, versatile, lightweight, lots of pockets
Cons: Small knife pouch
