2 keep a clear shield
without windshield wipers, we must resort to turning our head left and right at speed to get our visor to clear or wipe away away water with our gloves (a built-in finger squeegee is helpful) fogging can be minimized with a breath guard or a pinlock face shield insert-that's doubly helpful because when there's no fog you can keep water from getting on the inside of your shield by leaving it shut.
