If you wear neoprene waders, I figure you are going to come back damp one way or another, either from sweat or from small leaks. I don't stand in water except maybe 1-2 times a year so I use them to get where I am going, set and retrieve decoys and then I'm up on dry land for the most part.
If you are wet under neoprene, it's actually warmer than if you are dry. Your body heat will heat the water and it will be a great insulator. This is how wetsuits work, I would stay overly warm diving in December and have a pretty big layer of water between the neoprene and my skin all the time.
That, and I'm cheap when it comes to buying waders. If I threw them away everytime there was a tiny leak I would go through a pair every 10-20 hunts at least and I don't go through nasty stuff very often.
I will have to disagree on the notion that you are warmer when you are wet. When you are in a wet suit, you are in water that is above freezing by a decent amount. When its single digits, you are for sure warmer being dry under your waders than wet. Don't ask me how I know...
