One of the most popular sections of the GWTW Forum has long been the Swap Meet.  A great place to sell old, seldom flown kites or to get great deals on used (gently flown) kites.  Only registered users can see the Swap Meet section, let alone wheel and deal.  1000's (literally) of kites have changed hands thanks to the Swap Meet.
There are several more benefits to being a registered user, but you'll have to join our little community to find out all the "secrets".

Info's on the way, Jim.

SPF 15/20 -- I'm not sure what the diff really is. My understanding, though, is that's the MINIMUM recommended protection. If you're going to reapply it every hour or so, perhaps it would do. I don't think I've ever been that conscientious and would rather be extra safe with a higher SPF rating.

BTW, my doc's recommendation based on the research is for SPF 70 in the Nutrogena Helioplex line or, as the best, micronized zinc or titanium dioxide (physical blockers vs chemical blockers) which now are made in clear formulations.

Personally, I'm not going to quibble about a little extra degree of rating. If I'm going to apply it at all, I'd rather be safer.

Thanks so much Bob...........I guess when you get down to it, being right doesn't mean a lot with the Pharmacists I work with...........It would be so much more improtant to have that PDF file posted somewhere on this Forum (sticky maybe?) so all of us could have a chance to view, ingest, and pass on this most important info..........We all gonna die................but if we had a little more info, we just might prolong the obvious safety factors that seem, sometimes, to be ignored 'cuz of our passion.........thank you,

Was thinking...why would a hat have a spf rating? If it does not have holes in it, would it not provide 100% protection. Perhaps I am too simple minded to get it.

Actually, clothing has a UPF (Ultraviolet Protection Factor) - based on the percentage of UVA/UVB that is blocked - whereas sunscreens have a SPF (Sun Protection Factor) which is an EPA standard indicating a relative length of sun exposure before reddening with sun screen compared to without.

A normal-language explanation can be found here (scroll down about 2/3 way), but simply put, different fabrics, designs and construction methods can have different UV blocking characteristics.
Quote
The UPF ratings for level of protection found in the fabrics are classified byASTM International as follows:
Excellent UV Protection=UPF 4050+, blocks 97.5% of UV radiation
Very Good UV Protection=UPF 2539, blocks 96.097.4% of UV radiation
Good UV Protection=UPF 15- 24, blocks 93.3-95.9% of UV radiation

Hope that makes sense.

The lighter weight compared to cheaper hats sold me.

One can still get burnt from looking up in the sky at the kite and reflection off sand or water. Beyond that, the tightness of the weave or type of fabric varies on how much of the rays penetrate through.

When growing up on the farm, I never wore a cap. Later in life I went in for sleep apnea / CPAP testing. When they were hooking up the wires to my scalp, they commented that my scalp was thicker than normal and I must not wear a cap outdoors. Who would have guessed that as a side-effect? Not a "I'll live forever" teenager.
