This bag isn't really a bag by definition. It is actually a carefully layed-out series of flaps that can hug anything you want against your back. No, you can't throw a pencil in this 'bag', but if you insist on loose pencils, attach a pocket. It carries books, papers, bulky, and rolled items with ease. There is also a hip belt to keep it from swinging around while biking/running, padded back, inner velcro patch to attach a pocket of your choice, key clip, and external daisy chain and reflectors. You can fit just about anythign you want in this amazingly adjustable backpack. I think Dana Designs makes something like this, but I beat 'em to it. Too bad I don't have it on paper. The shoulder straps are paired webbing straps with reflectors. They distribute a big load nicely, and seat themselves more comfortable than a single piece of 2" webbing would. They feel good, and don't get sweaty.
