Fogging in a helmet is a common phenomenon, caused by condensation of moisture present in the air. Several factors can contribute to this:
Temperature difference : The main cause is the temperature difference between the warm, humid air you exhale and the cold, dry air inside the helmet. This condensation forms on the visor, reducing visibility.
Ambient humidity : The more humid the ambient air, the more likely fog is to form. This is especially true in rainy, foggy conditions, or when riding in a humid area.
Helmet Sealing : A poorly ventilated helmet or one that is not perfectly sealed promotes fogging. The humid air from your breathing then accumulates inside the helmet, with no way to escape.
Scarf and Mask : Wearing a scarf or mask that rides high on your face can also contribute to fogging, by redirecting your breathing into the inside of the helmet.
Sweating : If you sweat a lot, the sweat can evaporate and condense on the visor, creating fog.
How to avoid fogging?
The most effective solutions are sometimes the simplest. So, the first tip is to slightly open the visor . By letting a little air through, fog will tend not to set in. Obviously, in the middle of winter, this is not the most pleasant.
Stick a protective film
If you prefer to stay warm, you can stick a protective film . It will effectively prevent fog from appearing inside your helmet. The only problem is that it could come off over time. Another idea is to use spray products that are relatively effective against fog.
Installing a Pinlock screen
For a long-term solution, opt for a Pinlock screen . Its installation is not complicated and can be done in no time. You can find some on the LaCentraleDuCasque website .
Face mask
Wear a face mask that allows air to pass through your nose. This will prevent your breath from coming directly up onto the visor.
Hydrophilic treatments : they create a thin layer of water on the surface of the glass which repels condensation droplets.
Hydrophobic treatments : These modify the structure of the glass surface to make it smoother, which prevents water droplets from sticking to it.

How to make a natural anti-fog?
Regular shaving foam is a great natural alternative to fogging. Apply a thin layer to the inside of your visor, let it sit for a few seconds, then gently wipe with a clean microfiber cloth.
Another tried and true method is to rub a halved raw potato over the surface. The natural compounds in the potato create an invisible barrier that repels condensation for several days.
Marseille soap is also an economical and natural option. Lightly rub a dry bar of soap on the surface, then polish with a soft cloth until perfectly transparent. This tip guarantees protection for 48 to 72 hours depending on weather conditions.
How to soundproof a motorcycle helmet?
Optimal soundproofing of a motorcycle helmet requires several complementary solutions. A neoprene neckband placed at the base of the helmet significantly reduces air infiltration and noise pollution.
The specific acoustic foams, installed at the ears and chin strap, effectively absorb unwanted noise. For an even better result, the addition of custom-made earplugs offers additional protection without compromising the hearing of sounds essential to safety.
