My choose is the VentureSafe 25l Daypack from pac-safe.com. It’s a really good looking bag with Anti-Theft features and an extra laptop sleeve for the netbook.
It’s very ergonomic and comfortable to wear. I orderd the bag from my favorite outdoor specialist www.globetrotter.de. Only one day after placing the order online the package arrived. I hope that I don’t need to test the Anti-Theft features in real situations, but it’s good to know that it has it.
