I got one of these at the Wright Brothers Memorial shop. (Like I needed another backpack!) I am SO glad I got it! It is my favorite backpack I think that I have ever had! I love the map on the back of it. (Time will tell if it rubs off or not). But I just love the material it is made out of. It is sturdy, but also flexible, but does not fall over if it is not full. The pockets are set out conveniently with a top pocket for phone/gum, etc, and the bottom pocket has slots for pens and pencils, and room for keys or other accessories. There is a laptop sleeve as well.The laptop divider has a zippered pocket in it. It has mesh water bottle pockets on both sides. They are a little tight, but I can still fit a 32oz water bottle in it. The straps are very comfortable and have D rings if you need to attach anything on them. It does not have ports for a water bladder, but if you wanted to use it this way, I think you could repurpose the laptop sleeve area and run the straw out one side. Overall, a very nice back at a decent price point. I love this bag!
