How to stop helmet visor fogging?

There are several methods to prevent helmet visor fogging. Here are some effective ways to try:

1. Anti-fog spray or wipes: Apply an anti-fog spray or wipe specifically designed for helmet visors. These products create a thin protective film on the visor surface that prevents condensation and fogging. Follow the product instructions for the best results.
2. Cat litter: Fill a sock or small cloth bag with clean cat litter and place it inside your helmet overnight. Cat litter contains moisture-absorbing properties, which can help reduce fogging. Remember to replace the cat litter regularly to maintain its effectiveness.
3. Shaving cream: Apply a small amount of non-gel shaving cream to the inside of the visor. Use a soft cloth to spread it evenly, then wipe off the excess. The thin layer of shaving cream acts as a barrier against moisture buildup, reducing fogging.
4. Pinlock visor insert: Some helmets come with a Pinlock visor system or have the option to purchase one separately. The Pinlock system uses a double-layered visor with a silicone seal in between. This creates a sealed chamber that prevents fogging by creating a thermal barrier between the outside and inside air.
5. Ventilation: Ensure your helmet's ventilation system is functioning correctly. Proper airflow can significantly reduce fogging by regulating the temperature and humidity inside the helmet. Open vents or crack the visor slightly to allow for better air circulation.
6. Breath control: When riding, try to regulate your breathing to minimize the warm, moist air from escaping into the helmet. Breathe downwards or exhale through your nose if possible. This can help redirect your exhaled breath away from the visor and reduce fogging.

Remember, helmet visors can fog due to temperature and humidity differences, so implementing a combination of these methods might provide the best results. Experiment with different techniques to find what works best for you and your specific riding conditions.
