Hi all, My current Wenger backpack is starting to fall apart after 1 year. I would like something a bit smarter but it still needs lots of functionality. I don't need to go camping with it for a weekend but I would like it to have the following functions: 1. Relatively waterproof 2. Internal / side / front pockets for tools / pens 3. Preferably black or brown 4. Laptop compartment would be handy 5. Budget is not a problem, I just want something that will last! Any recommendations will be very much appreciated!
