  He talks about wrinkling and skin damage (sunburn?).   Well, if you are only 
  concerned about sunburn and wrinkling, then go ahead and depend on the 
  canopy for your protection. 
  
  However, nowhere in Eric's post does he mention SKIN CANCER! 
  
  The UVA range of the sun's spectrum has a longer wavelength and penetrates 
  right through your canopy and deeply into your skin.  There is a large body 
  of research which ties UVA exposure to skin cancer.

  The canopy does provide some protection, but it is not sufficient.  The best 
  protection is to cover yourself with light colored clothing and a good 
  protective hat while flying.  Certainly a broad spectrum sunscreen should be 
  used as well. 
 
 I certainly agree with these cautions, and they are needed even more 
 outside the cockpit, where glider pilots also spend a lot of time. 
 
 I read the article, but now I'm confused that the UV Index doesn't seem 
 to account for UVA, and the article didn't mention it. Can you describe 
 the reason or point to a resource that does? Perhaps the UV index hasn't 
 kept up with the science?

Hi there,
 
Eric makes an excellent point...there are some questions that we need 
to ask....and he is not the first one to raise up the point. Great job 
Eric....
