52telecaster, your responses are polite and insult-free. I don't think you know how the internet is supposed to work. (just kidding)

As long as I'm here I want to mention I've been bald for 15 years and have never had an issue with burning or spots with any of the mildly vented helmets I've worn, even though my arms, neck and shoulder are prone to burn on rides over 2 hours here at 6500ft...less time above 7000ft.

And if I walk in the sun without a hat for more than 45 minutes, my head burns.

With the growing list of physical challenges to biking as I close in on 60, at least sunburn under the helmet isn't one of them...yet.
