Just what my son was looking for- holds his 15 inch computer, mouse, etc, plus some books without looking overloaded. Comfortable, easy to access. Can't say about how well it will hold up as we just got it but it comes with a forever guarentee so I suspect it will do well. Also seems to be very well constructed. Several pockets including one zipped pocket, but not so many that you are spending all your time searching around trying to find things.  Also came with several extra sets of small straps in different colors to allow for a bit of personalization. He is thrilled with the bag.
