If there is a reasonable chance I could go for a swim, I put this on...



The Kokatat Supernova is very affordable compared to most dry suits and although it isn't designed for long swims, I have taken quite a few in it and it does well. A little leaky at the neck due to the neoprene gasket, but very minimal. It is quite light and packs around very easily as well. I have fished and floated quite a few long days in it and I would say that it is equally as comfortable as my waders, perhaps more so.

Otherwise, as Neal said, a good neoprene or stretch wading belt, a well fit rain jacket, and a properly fit and functioning PFD is about as good as you are going to do.
