I wear an old style cotton cycling cap under my helmet. I need to shop for one that has high SPF to prevent painful sunburn, and investigate what it takes to stop the bigger half of the UV problem, radiation that can cause skin cancer.

A good place to peruse is Amazon and just type in the search feature for "skull caps" or "bicycle headcover," etc. Buy from whoever you want once you have decided.
Good luck on getting something that is exactly right for you.
