I purchased a new wonderfully lightweight Bell Alchera helmet this year. Of course, one of the reasons this helmet is so light is that it is very well vented. By mid July, I noticed I was starting to sport some very "Sci Fi"-like tan marks on my forehead starting at my hairline and running towards my eyebrows, despite wearing sunscreen. My family started taking to calling me "Alien" in their ever so sweet way![]()
Eventually I was forced to buy a headband to protect that area. The marks are only now starting to disappear.![]()
