Redington also makes zipper waders for around $200 I think but I have not used them so I don't know how they are.
I just bought waders for my wife and when I was talking to sales person she told me that waders for women are cut much different and that most women prefer womens waders. Also the stocking feet are smaller on womens waders in comparison to the size of the wader. I ended up getting my wife a pair of Frogg Togg waist highs cause they were cheap and I didn't know if she was going to hate fly fishing (she really enjoys it now).
Ramsey Outdoor (quality store down here by me) has these on sale. http://www.ramseyoutdoor.com/product...379/index.aspx I would have gotten these for my wife if I knew she was going to like it.
