This bag is perfect for a 4-day business trip. It holds a suits well as well as extra shirts without messing them up. It is sturdy and takes a beating without a sweat. This bag fits the American Airlines carry on size rules and I use it every week. Just beware that if your plane is an MD Super 80, it fits much better on the overhead over the 3-across side than the 2-across side. And don't stuff the pocket otherwise the gate crew will make you drop it in the measurement sizer box and you'll have to empty the pocket out. Also, get your own TSA lock. The one they give you is junk.
