Take on the Jansport backpack

35 years ago, I desperately wanted a Jansport backpack and after begging and pleading I finally got my parents to drop some stupid amount of money on a bag which looked exactly like the bag every other kid had. Fast forward and my own kids are looking for the exact same backpack I had as a kid and it's still twice as expensive as any other bag. You'd think the extra money pays for better quality not just a brand but honestly in 35 years plus of making these things, they still have bit figured out that kids will jam these things full and then before you know it, the zipper will get stuck

My kid's zipper is so stuck, I need jaws of life to have a shot to open up that bag.
