Shwew! So glad they added SPF to these shirts because I was so busy getting an all over burn and tan wearing my long pants and my shirts. When I was a kid i'd come home and have the worst sunburn on my ass from all that sun shining through my jeans. Now I can wear a nice short sleeve shirt while I'm out on the river all day and get that nice farmer's tan i was never able to get before from simply wearing a short sleeve shirt. IS THIS MARKETING CAMPAIGN CRAZY??! EVERY SHIRT I'VE EVER WORN IS SPF 2,000. Now it's a sales point for marketing? Try "any thin cotton western style shirt off the rack of farm and fleet in the year 1978."
50+ if really pale and going to tropics. For clothes I only need upf 15 because clothes protect better than sun screen. I also tan so I do not burn when I where clothes.
