I'm a big 5.11 fan and like the look and features of this bag. However, as a business travel bag it won't work because there's no "suiter" feature on the inside of the the main compartment flap for hanging a suit or button-down shirts. Do this on your next version of this bag, and I'm in!
The DC Flight Line roller is by far the best carry-on piece of luggage I've ever owned. Extremely light weight and well constructed. I travel over 150K miles per year and this case has never failed! The grey color is very easy to spot in a sea of black bags as well.
