Meh. The bag is fine. Comparable in size to the Large size Timbuk2, and cheaper, and sans Velcro (which is nice). But as the other reviews imply, this bag is very large. Too large I would say. I'm 5'8 160lbs, and the bag was wider than me when on my back. If I were walking down the aisle of an airplane, and I had this thing loaded up and over my shoulder, it would probably hit people on both sides as I walked past them.
In conclusion: The construction of the Timbuk2 seems to be a bit nicer and better thought out, but, not $100 better thought out. So, if you need a huge bag (I fit my 15inch laptop, 3 law school text books, a 3 inch binder, and still had room to toss in a pair of sneakers and gym clothes), and you don't have the money to burn on the Timbuk2, then this bag will do you fine. Although, I would imagine that actually carrying this thing around while it is fully loaded would be quite cruel to your shoulder.
