I just sent waders to Simms and Patagonia for warranty/repair and thought I'd forward on the results. The Patagonia waders are quite old (dating from around 2005) but have been used very little (I actually never remembered owning these and found them stashed in a closet when I cleaned out my office, so while they may be old they have very little wear). They had significant leaking booties, a seam leak in the crotch and leg, and a few minor pinhole leaks. Patagonia classified all these as "usual wear and tear" and wanted $65 to refurbish the waders. I decided not to have them refurbished as I already have two pairs of Simms. At the same time I also sent in a pair of Simms G3 waders (dating from around 2006) that have a lot more wear than the Patagonia's, and they had a slightly leaking bootie, a major seam leak in the crotch, and a few minor pinhole leaks. Simms covered the booties and seam leak under warranty and charged me $15 for patching the pinhole leaks (which is quite fair). They also replaced the seat (had minor wear and scuffing) without my asking under warranty. Also, I sent in a pair of Chris' old Patagonia waders (about 2005) with very little use, that had major seam leaks caused by the tape lines chafing on the inside of the legs and Patagonia would not cover them under warranty (that surprised the heck out of me, because these leaks are caused by the tape line being on the inside of the leg and in no way are the fault of Chris).
Quite a difference in approach, between Simms and Patagonia and I know who will be getting my business in the future!
