Here is the best sun protection combination. Other's have mentioned it already. Start from your head and work down. A great sun hat. Baseball caps don't cut it on those really hot sunny days. Your neck is exposed for long periods of time. Great pair of polarized glasses. A must for eye protection. A buff, covers what the sunglasses do not. An outdoor long sleeve shirt. With the materials that are being utilized today, you get the best of both worlds. Sun protection and a minute cooling effect. A great pair of sun gloves. Only your fingers from the middle knuckle up will be exposed. These things are so light you don't know you even have them on. Pants. Similar to the shirts. They are very light weight extremely comfortable and offer excellent sun protection. Lastly, your feet. for me, a good pair of socks, and some crocs and my feet do not get burned. With what I described above, you are covered from head to toe no real need for sun block unless the buff doesn't work for you. Other than that only half of your fingers will be exposed. Can't ask for better sun protection than that. Oh....lastly. Hydrate, hydrate, hydrate. If you are out fishing for let's say 6 hours and you have not pee'd at all. It's a pretty good indicator you are dehydrated, even though you may not be thirsty. If you do pee and it looks like applejuice you are most likely very dehydrated. Proper hydration is critical for fishing and dealing with this summer's heat.
