Okay, I posted those other pictures from my phone. Hopefully these work:
I haven't contacted Redington as their warranty (even for manufacturer defects) is only for one year on waders and I've had these for about 4 years now. Additionally, the original sticking of the zipper could have been a defect, but from what I've read it was leaving them done up all the time that probably caused the eventual complete failure of the zipper. Apparently you are never supposed to store zippered waders done up as any pressure and severe bending can cause the zipper to fail.
From what I can see, I could remove a few teeth, rethread the zipper at the bottom, zip it up a couple of inches and apply patches and a ton of aquaseal to waterproof it and then the zipper would just begin a couple inches above where it did originally. Kind of a redneck solution, but I don't really want to put a ton of money into them at this point. I've also had them leak on me just about every season. The fit is great, but I haven't been that impressed by the quality of these Sonic Pros.
Thankfully, I have the original design which wasn't near what they cost now. I think I'll be switching back to Simms when I can afford a new pair.
ANYWAY, I welcome any and all suggestions on how to fix this.
