I've been using Orvis Guide-Pros for the last few years, but have been unsatisfied. I haven't made it out on the water a lot in the past couple of seasons, but I find that the guide-pros have failed on me after only a season of medium use (and proper care) - fortunately with the Orvis warranty means that I've easily gotten replacements.
Due to some wonderful circumstances, I'll be on the water a lot this year, with something like 60-70 full days planned. I'll be fishing in several remote places on long trips of 2-3 weeks in duration, so leaky waders will be a real pain to deal with - the nearest Orvis shop will be 1000-1500 miles away.
I've been thinking about going for the Simms G3 waders, hoping that the bump in cost will mean that the waders will be of better quality and more durable. Before doing so, I'd like to get some feedback before laying out the >400 bills.
