Osprey Farpoint 40 Travel Backpack

You see a lot of these bags around airports and now I know why. Great build quality, they fit nicely on your back, no pinch points, it breathes nicely. Just got back from 16 days in 4 countries, solely using this bag. Expensive but quality. As noted above, many people have these, a touch of customization to make your own stand out from the crowd is recommended! Had a gentleman pull mine from the overhead, we had identical bags other than a carabiner I had on mine.
