This is a great topic of discussion!! Thanks for raising it, Coug.
In 2011, a very good friend of mine who worked as an excavation contractor lost his life due to melanoma. My friend was a big refrigerator-sized man, and I and others considered him totally invincible. This was a wake-up call for me, because I realized if this could happen to him, then what chance would a pipsqueak like me have. So, I found a good dermatologist (a fisherman himself). The first several visits for me were pretty much cut and stitch or liquid nitrogen freezes on face, chest and hands to remove damage I’d done over four decade in the outdoors.
Now, when I’m out fishing during the warm months I pretty much look like those people in Raspberry-patch’s pictures. I use a 50 UPF sun hoodie (Simms, Patagonia, and Columbia), a buff, ball cap, and sun gloves. I put 70 to 100 SPF sun screen on my nose and cheeks and I pull the hood up over the whole thing. When steelheading I wear the hoodie and neck buff under my warmer jacket. I really like the sun hoodie because it cuts out the peripheral side glare off the water surface, which enhances your vision through polarizing sun glasses. I wear 50 UPF pants too in summer when wet wading. I’m so covered up, seeing me you couldn’t tell my gender, race, or guess my age bracket – totally incognito!
I have one of those wide brim sun hats too, but frankly I like the ball cap and hoodie combo better because I feel it covers my neck better, offers more protection from reflective sun, and stays on my head better in the wind or in a fast moving skiff. Also, my buddy has less chance of hooking my hat when fishing in the raft – lol!!
