I was a little uncertain when I ordered this backpack because I have a 17 inch laptop.  Boring black backpacks are not my thing at all!  So I checked out the dimensions and ordered knowing that I could return if needed.  The backpack fits my laptop perfectly!  Granted, it does not fit in the padded compartment, but there is still plenty of protection for it. There is also space for my purse organizer so I don't have to carry a second bag.  There is room for my Kindle or book. And still more room! I walked around with a complete load of what I would normally carry and I had no problems at all!  The weight distribution and padded handles make this comfortable to carry.  I really like the design and great organizing capability.  So far, I'm very pleased with my new backpack and would recommend it if you need the space.
