While typing away furiously at my favorite coffee haunt I caught the lovely brown of a messenger bag slide past my peripheral. Sure enough! This bag was purchased 15 years ago in Germany and has held up well to moderate use. It spent several years tucked away in a closet where it acquired a severe drywall stain but otherwise looks none the worse. All the zippers still work great, none of the stitching is frayed, and the leather is holding up well.
Enjoy!
