One of my homie's used to work at Dan Dee Sporting Goods in Sweet Home. He swears by gear made by Rivers West (made in America).
Plus, I personally own one of their camo sets (hooded parka / bib overalls); and I LOVE them! They are also made for EXTREME cold conditions, and designed for places like Alaska, Wyoming, Montanna, etc. in the dead of winter. You don't even need to wear much under them (no thermal long johns needed)!
So, if you're gonna fish through the winter--that is my recommendation.
Here is their link:

P.S. I forgot to mention: the Rivers West gear, is primarily made for extreme cold weather hunting (at least my outfit is made in that regard). But, I see no reason why it won't work for fishing. I intend to try mine out soon.
