This bag is perfect for what I got it for. I carry an ipad 4 and moleskin sketch book with a few pens, pencils and small watercolor set in it. The inside pocket does have a zipper, so if you don't have a cover on your ipad I could see it getting scratched up.

My only real complaint is the strap length. I'm 6'5" with an almost barrel chest so carrying it across body looks ridiculous. I'm currently looking for a longer strap to attach to it. Until then I'm shouldering it
