I have a couple of I believe micro fiber long sleeve pull over shirts designed primarily designed for salt water fishermen. One has a Marlin jumping on the back side.
Any sweet just evaporates quickly.
I am considering buying a few more. Not too fashionable off the water but maybe not affordable since Cabelas was taken over by Bass Pro. Everything is much higher in price at both now.
Perhaps some are available on line.
Besides those, I have several "Cowboy" shirts that are heavy with double shoulders and upper body to fend of the sun. The ones I prefer if they get wet however feel like 20 lbs.
The average shirt, is not good protection from the sun. I have gotten sunburn wearing just polo shirts on shoulders and back and upper front of body. These are the Under Armor Micro fibers too. And tee shirts migh as well wear none, colored or not.
So still going to have to wear Sun Block under chin, neck, face and ears plus wide brimmed hat...or not leave Tn where we have had only five or six days total since November of sun. :)
