I got this bag because I wanted the largest of this type that could be used for carry-on.  This is it.  I wish I could say 4 1/2 stars, just because I would have liked two compartments, but it does have one smaller pocket on one side and a larger pocket on the other.

3 days worth of clothes only filled this about 1/2 way - it's really big.  Looks classy, and doesn't look just like everyone else's black roller bag when coming off of the baggage return.
