What is your favorite?? Tactical is mentioned because I like the look and they are often made with stronger materials. Right now I have a Vanquest Messenger I which I love as a catch all for most small things. Looking for an over-the-shoulder duffle style that has end handles (for making it easier to stow in the overhead bin). Foliage is my favorite color, but would consider urban grey or black combos. What works for you? Pics are handy. Thanks for your help.
