merlin, my favorite long sleeve is by Columbia Sportswear Co. of Portland. White, light weight and vented all the way across the back with fine webbing on the inside that covers the vent. I don't recall, but it does have a SPF rating that was pretty high. My only gripe is the darn thing is made in Sri Lanka.
Hat, always my hat. Again made by Columbia. BIG ole bill with retractable flaps and vented with webbing as well. If you don't mind the 'Elmer Fudd' look, it's a great hat. Again, made in Vietnam....geez! Oh yeah, it also has a strap for my pin head.
Last but not least, two pair of wrap a round sunglasses. Mine are prescription and I like for all my glasses to be polarized. And since I dropped a pair off a very deep dock in Tampa, I always use a lanyard on all pairs. BTW, I did retrieve them with a borrowed set of fins, but it cost me my hearing for three days! I think to top it all off, I'm going to invest in some of those 'Bozo' shoes for on deck stability and floatation, just in case!
Well, with this get-up (sans Bozo shoes) I made a 1200 mile passage without being burned to a crisp, and that was without the zinc grease or sun block, so the outfit works. Then, I go to the pool with the wife for an hour and a half last Friday and I'm just now able to breath without my hair screaming. Yeah, I'm working on a solar panel!
