Packs easily, rolls nicely, zippers smooth. But be careful, on a recent long trip I packed it pretty full. I was embarrassed when it wouldnt fit in the overhead bin on Delta/Skywests Embraer E-175. Unlike Alaska, who checks carryons on the tarmac when you fly regional planes (like the Bombardier Q 400), Delta does not. So until a nice flight attendant bailed me out I was that guy with a line of people waiting for me so they could get to their seats. Just be aware you can pack this bag to the point it will not fit into some overhead bins.
