I've had my Mythwear NERV bag for... gods, ten years now. It finally started to deteriorate last year and its decline is accelerating. I'm tempted to replace it with something substantially similar, given that it does what I need and has held up through a decade of abuse and neglect, but if anyone has any suggestions for a replacement, I'll take them. I prefer messenger/courier bags to backpacks, and its primary uses are to carry cards, game-related-stuff, and books to/from the card shop, and to carry books and personal electronics when traveling. Laptop bags need not apply.
