One strap is fraying and ripping off my backpack… and the metal attachment for the pull tab broke, not just the tab itself which could have been replaced. But it’s a two pull zipper so could just open and close with the other tab.

I wonder if I can repair it securely or if the strap would just tear out again or the seam would split. I could reinforce it by doubling the end over which might make it shorter or maybe by using a patch.

I could just replace it but the equivalent now is $40 when the same thing used to be $20, plus it would be a shame to send a still working bag to landfill.
