After years of simply using a baseball hat, I've come to the conclusion that there has got to be a better option for cold weather fishing. I like the bill of the hat, as it helps when I wear a rain jacket and hood to keep the hood out of my line of sight. But Baseball hats just don't provide any real insulation...What works for you? Ideally I'd like to find something that has a bill, is light weight, water proof, and provides a good insulation. Any ideas???
