I had read the dimensions and approximated them with a tape measure, so I thought I was ready for this bag. When it arrived, I found that it was considerably larger than I had pictured. This is not a complaint: I was hoping for more room but bought a smaller bag to save money. It is well made, roomy, and easy to use. If it had a divider or some other form of interior pockets I would give it five stars, but in every other way it is a great bag.
