As I age I seem to need more protection from the Sun. My Friend Loretta who is only 80 and very fair wants the Sun. She is also very concerned that I cannot see traffic as well with the hood or the Bimini top. Western Washington is mild, but Central Oregon and California can be very hot. Eastern U.S. off the West Coast is often very hot. Mrs. Button could not stand the Sun for any length of time. I started to use Bimini tops to protect Her more than anything else. But as I have them, they are easy to store and somewhat waterproof and easy to wash, I use them a lot. My DHC has the rear window with zippers so I can get good air circulation with that. Remember I often put in long shifts driving. Just from a fatigue standpoint they help.
