"Last night my wife looked at me and said I had sun tan stripes on my forehead and the top of my head, yup my hair has thinned some over the years. I have a Giro helmet with large vents on the top that open to the sky. Does any one have recommendations for helmets that have good ventilation while at the same time do not have large vertical openings that allow the sun to shine directly down the user's head. Thanks for your ideas."

This morning I put some non-greasy suntan lotion on my head, I will keep trying this to see how it works for me. Fortunately I live in a temperate climate, northern CA, but putting on a skull cap or helmet cover would be just to hot for me.
