Fairly roomy, though it holds less than you think it will.
Very comfortable to wear.
If you want a bag for occasional light use, this is okay for the price.
Within two days, the stitching on the inside pocket of this bag had come away, pulling the piping along the top of the pocket away from the pouch.
Within a week, the shoddy looking stitching on the front zipper pocket had come away.
The zips are hard to get at, even when the compressor straps on the side are not in the way - adding carabiner clips helped, but it's hardly an elegant solution.
The organizer on the inside is floppy and not practical to use.
Those mesh pockets on the side aren't deep enough to hold a water bottle of any size. Or actually anything that you might expect to want to put in there.
