Stitching-related zipper failure, or the zipper itself? I feel like stitching in general is where Jansports fail first.... you have to abuse them pretty hard to wear out the material or bust a zipper directly, but the stitching on Jansports is not amazing. Don't get me wrong... the price/performance/durability of Jansports is INSANE but they maybe are venerated a little too hard
