For me suiting up for fishing is an event, I get cold easily so this is my normal winter wear.

Polar Fleece pants

T-Shirt with a Polar Fleece shirt over it

1-2 pairs of Polar Fleece socks depending on how much I plan to wade that day.

Then on the outside of the waders I put on a Polar Fleece coat, then a Gortex rain coat.

Baseball cap, stocking cap, or Gortex hat depending on the weather.

Always bring a pair of wool or polar fleece fingerless gloves if your hands get cold like mine do.

Thats usually enough to keep me warm except for my hands I have not figured out how to keep them warm all day yet.
