Review on Waterproof Business Laptop Backpack for School Travel and Work - Fits 17.3 Inch Laptop with YKK-3 Pocket by Michael Boyle

The problem with this backpack and most rectangular backpacks is that they are cumbersome to carry unless full. Since all my stuff falls down and the top 30% is empty, it creates a crease around the top of the backplane. Which makes it a bit uncomfortable. Also, none of the inside pockets have zippers. So if you lay your backpack on its side, expect them to fall out. Still, it's a nice package. But as usual, when something looks good, you pay for functionality.
