I had a Jansport-like Outdoor Products bag I purchased for a day's minimum wage pay when I was 12; Mom thought I was nuts. Over 15 years, they repaired it once and replaced it twice. On the fourth attempt, they objected. I can't blame them, they were honorable, even if they didn't seem to honor their "lifetime warranty" literally.

I've revisited their warranty statement in recent years; they seem to have reconsidered, and seem recommitted to the BiFL warranty concept. Not sure its worth it for many with today's shipping costs, but if I was looking for a new BiFL book bag-backpack, I'd give them a chance alongside Jansport.
