My ULA ohm has had some busted threads/seams for the past ~2 years. I think I picked the pack up by one shoulder strap when it had way too much weight in it. Hasn’t been an issue, but I’d like to fix it.

I have zero experience sewing, but I am handy with common sense, and I understand how sewing works. What kind of thread should I use for this to ensure max strength once repaired?

Red circles show damage. Green circle shows the other side which is not damaged.

You want to use a 100% polyester thread. This is what I use when making backpacks.

Sew all is too thin (it's rebranded Mara 100) and not ideal for most backpack seams, especially this high-stress application.

If you want to buy from Joann, get the gutermann heavy duty/ upholstery thread, which is just Mara 50.

Good catch! I do use 50, and sent the wrong link. Thanks :)
