What's "normal use"? Here was my "normal use" as a student in the 1980s and 1990s. - 4 or 5 large books at once, bag often fairly bulging - Zipped and unzipped probably > 20x daily - Dropped onto school, home, and schoolbus floors dozens of times daily with various levels of care - Some walking, some weather exposure (less for me than many others) - One strap always carrying 100% of the load because the style was to wear it over one shoulder; it was never acceptable to wear it with a strap over each shoulder as actually designed Anecdotally I didn't see a lot of $50 Jansports lasting multiple years under those conditions and even if they did they would be pretty grungy. Now... today as a middle-aged adult? Yes, a $50 Jansport easily lasts me 10+ years, probably more like 30, basically a lifetime purchase. Also... today as a student? I guess it's less physical books and more Chromebooks so sure yeah maybe $50 Jansports can be lifetime purchases for kids, why the hell not
