I just finished "Bike Across Kansas" - riding from east to west so my wife and I were facing the sun for over 4 to 5 hours for seven days. Used SPF 50 - still had sun burn. I had to pick up an after market visor for my road helmet before the ride. The visor wasn't long enough to keep the sun out of my face for 3 to 4 hours. I am looking at "Carbon Spider Carbon Fiber Visor" to replace the small visor that I used on the trip. I discovered the visor while scanning bentrideronline.com.
