Backpack repair question

Because of the location of the holes, I think it would be very difficult to repair by yourself with a regular "home" sewing machine… perhaps you could bring your own materials to a shoe repair place or an upholsterer and have them do the work for you.

If so, I would attach a piece of thick faux leather around the bottom half-inch of each stay (blunting the end of the stay), then have them sew a nice thick nylon cordura patch over each side of the pack's bottom, where the stays poked holes.

Alternatively, you could contact Mountainsmith's customer service, and see what they might charge to repair it for you…

That no sew, heat bonding/fusing stuff for fabric seems to be quite strong and durable stuff. You know, the stuff you use an iron on?

Perhaps get a heavy duty piece of nylon and bond it on the pack using the above?

A picture would help.

I suspect reinforcing the interior stay sleeve would require taking out some stitching and adding material with a speedy stitcher or heavy needle. Slow, but effective. You might be able to laminate some cordura or 2" flat webbing in using seam grip if sewing is too much bother.

Bring some cordura nylon.

Otherwise rip out the main seams on the pack (a real project with bound seams) so you can get the pack under a standard sewing machine.

Hand stitch it using a speed stitch as someone else suggested. If you go slow and steady you'll have a great repair, even with no experience. Machines are nice but for small repairs they're often not worth the trouble.
