I'm looking for a bag for taking on holidays when you expect to be out and about doing stuff all day. I prefer a backpack, so that I have my hands free and it doesn't hurt my back if I'm carrying loads of stuff. But I want something that looks nice - not a sporty type backpack. I have a Knomo laptop backpack that I use for work, but I don't want to spend so much money on a day bag. Any suggestions would be appreciated.
