I've been thinking of getting a new roadie helmet for next year that will be lighter and better-vented than the MTB-oriented helmet that I've been wearing. But then I started thinking of the possible effect of the sun through those vents on my bare scalp.
There is nothing more painful than a sunburned scalp, and I am rarely outside without a cap on sunny days. And the only thing I could think of that could be worse than a sunburned scalp would be a scalp that is sunburned with a helmet-vent pattern! I guess I could use sunblock, but putting sunblock on my head also doesn't sound too appealing.
Is this a valid concern? Anyone else have any experience in this area?
