Ice Fishing Bibs Elastic Repair

After years of use on my ice bibs the straps that go over my shoulders is loose.

Do you just find someone that can sew that thicker material and have them tighten it up or what
are peoples ideas on how to regain that strength as I have the bibs all the way tightened
and still a little loose.

Thanks in advance.

i redid the elastic on my bibs myself a few years back. i ordered heavy duty stuff on amazon along with new clips too.

I used my wifes regular ole sewing machine.
