I've used this duffle bag and traveled all over the world, many times.  If you've ever seen the movie "Up in the Air" that resembles my life, living out of a suitcase... well, this is my suitcase of choice.  It's taken an incredible beating time and time again and it just keeps on being reliable.  This is actually the second of these I've purchased since I needed more things for an extended several week trip.  I figured I'd replace my original with this one, yet the original keeps on holding up.  Keep waiting for it to fall apart but it looks like I'll have to keep waiting a lot more years for that to happen.  Plenty of room, great build quality, a good buy.
