I fish some in Florida and a couple of years ago I found the "buff", which is just a semi elastic material that is really cool to wear. I never thought I'd like something like this around my neck and face but I love it. I keep it down around my neck until it starts to heat up, then I pull it up around my ears. It fits under a cap, so I like wearing a baseball style cap and this protects my neck and ears.
I never would have bought one, but my Florida buddy that I fish with loaned me one and I really liked it, so I got one a Walmart in Clewiston for around $15.
