I have a set of Cabela's Guidewear insulated waders (the chest-high version) I use for duck hunting and wade fishing. Mine have the 1600g insulation fill. This piece of gear is one of the best I've owned. Boots are solid, comfortable. I stood or sat many hours in the cold and wet and never had an issue. Not sure Cabela's markets the Guidewear brand any more but they do have similar (same?) products available under the Cabela's label.
