I work for the railroad. Always travel for work. My life has to fit in a bag. This is the best one I’ve found, you will pay for it, it’s not cheap! But it has a lifetime warranty. The folks I’ve worked with recommended it to me, either they had no issues with it at all or they got a brand new bag of the manufacture was unable to repair it. Here’s the link to red oxx
