This is another good sun protection product I've been using for a few years. I don't use it all the time but when tuna, albies, or other species that keep me out there dawn to dusk are around I prefer it by far to sunscreen. It looks uncomfortable but it's made of Coolmax and is very comfortable even in dead still air.

Combined with a hat and sunglasses you don't need to use half as much sunscreen if it all. Don' forget feet and hands though.
