This bag exceeded my expectations in quality. It's every bit as good as a $300 messenger bag you'll find in a downtown store. The leather portions are thick and well cut with quality seams. All of the zippers are high-quality metal that run smoothly, with leather riveted (not stitched) tabs. The magnetic buckles are of good quality, but could use a little more stickiness. The strap is excellent and highly adjustable.
The bag also comes with a 1 year warranty.
I expect this bag to age very well. Couldn't be happier.
My only complaint about the bag is that some areas are single-stitched where I would prefer a double stitch, such as where the bottom leather connects to the canvas, to be on the safe side.
