FWIW - I tried one pair of redington waders about 10 - 12 years ago - called Barrier Flex. From my experience, they were total garbage. They leaked within the first month or so. And after getting them repaced, the new ones leaked just as fast. I couldn't even get a full season out of them.
That said, I ran into a guy on the Delaware river this past spring who had a new pair of redington waders that he called claimed were like a guide weight. Can't remember the model #, but they looked pretty nice, and had a zipper. I think he told me that the price was under $300, and that they had a 2 year unconditional warranty.
