I am in the market for a new pair of chest waders.  I just discovered (the hard way) that mine are dry rotted in the seams.  I haven't shopped for a pair for so long I don't even know were to start.

Waders have, like everything else ...came a long way. Read up and buy with best pair you can. They tend to hit ya hard in the pocket book! The neo waders are worth every penny on thos ecold mornings

We hardly have what I consider"cold weather" here in Va. and  I have not had any problem during duck season, average temps can range from  freezing to mid 60s'  Only time I've been "real hot" with them on is trying to brush/build blinds in late Aug-Sept.   Won't do that again!

Yes they do, I think average is 3 grams of thinsulate, you also can get 5 grams.  With the temps you discribe, sounds like the 3 would be fine.... but it's your cold butt if it's not, just kidding
