Rainy conditions, cold mornings, and hot, humid days can all cause your helmet shield to fog — especially if they fit too closely to your face. While close-fitting helmets may enhance aerodynamics, they don’t allow the heat coming off your face to escape efficiently enough to balance the cold and/or damp air rushing at you. Here are some practical steps you can take ranked in order of effectiveness.
- First and foremost, the best way to stop your helmet shield lens from fogging up is to utilize the height adjustment feature located where the retention system attaches to the helmet at the top of the head, this mechanism slides adjusting the angle that the helmet sits at which can allow more air to flow behind the helmet shield lens.
- Keep your helmet shield lens clean as clean lenses are less likely to fog. Run warm water over the lens, using enough to rinse off any dust or dirt, then use a clean and dry microfiber towel to dry off the moisture. A lens cleaner such as Rudy Project’s Spray Lens Cleaner also works nicely when there’s no clean water available.
- Store your helmet shield lens in a case or pouch when you’re not using it. This is an easy step to forget when you’re in a hurry, but taking a few extra seconds to store your shield properly prevents the lens from picking up dust and dirt.
- Try an anti-fog spray. These sprays contain a hydrophilic ingredient that prevents moisture from bonding to the lens. When applying, remember to wipe the lens completely dry with a microfiber cloth before wearing your helmet shield lens.
