Water resistant replacement for leather

Hello:

I am trying to find something that can replace leather cord for
pendants- something that you can knot when needed- something that
will not mildew and is water resistant. And something that does not
look cheap- There is this one desginer Jill Platner who uses gortex
cord but I have no idea where she gets it- something like that could
be good- or a super strong flexible nylon cord 1mm - 2mm thick. Any
suggestions?

help!
