Best money I ever spent for staying warm and dry was for a good pair of breathable, zippered waders. Other than the warmest months of summer, I'm wearing them. I can't stand for my feet to be soaking all day and on my particular kayak, I've always got 3 inches of water in the foot wells. Catch a wave over the gunnels and I'm sitting in water the rest day, no problem with chest waders. Fish slime all over me, no problem. In the summer they are great mosquito and sun protection. Driving rain in the summer then breeze, I'm still warm and dry if I'm wearing a good light weight rain top, dressed to swim in winter with dry top over the waders. I'm starting third year on the ones below.
