When I started fishing we didn't have all these new fangled toys to play with. A sweat shirt and a Rain coat was what was used. It kept a body warm in the coldest weather. Sure you would sweat a lot but that was one of the joys of fishing. All you had to do was stop and cool down a little and then get back to fishing. I bugged my wife to get me a Gore-tex rain jacket one year. It hangs in my closet. It's been there for three years now. Just waiting to be used. But in my old age I've turned into a warm weather fly person. I don't go out unless the sun is shining. The rain be damned.
