My experience with Simm's repair is similar to what ScottV mentioned except it was a a set of Guide waders that had maybe 10 trips that leaked in the crotch area. They stated they would not repair the waders because of mildew, even though that was no where near the leak area. When asked if there was anything they could do they said "no". To add insult to injury they then wanted me to pay return shipping on leaky waders. I now use Patagonia waders who provide excellent service.
