Thanks. Basically I want the sturdy laptop backpack you got from HP 10 years ago with a clever way to pack clothes and ideally waterproof bottom (rubber/plastic) so that I don't worry when having it sit on random floors at airports or train stations.

Having a subdivision of the main compartment bigger than 2 is also important. Laptop, papers, cloth, food maybe.

I'm in Germany and looking for a shop nearby where they have a diverse selection of bags to inspect. I'm kinda tired of ordering bags and having had to send them all back. Amazon is threatening a penalty for returning too often, so there's that :).

First world problems, right?
