The “hidden” pocket is a complete waste. You can only access it if you expand the bag, and heaven help if you put something in there that the TSA doesn’t like (mine was a baggy with change) they can’t find it and you have to show them how to get to it . . . otherwise, it’s a decent bag, seems to hold up okay to travel (weekly traveler for business) and is perfect size for overhead bins and can hold clothing for 4 days.
