I went through three (no-frame, daily commute) backpacks in slightly over a year a while back - they all failed in different ways. It annoyed me enough that I spent time looking for a well-made one, and settled on a (noncustom) leather backpack. Sounds very similar - it looks nothing like a modern bag, is not very adjustable, a bit heavy in comparison, super comfortable to wear and I'm pretty sure it will outlive me.
