When it comes to snowmobiling, a foggy helmet can really put a damper on the fun. Trust me, I’ve been there. You’re all set for a thrilling ride, your heart is racing with excitement as your snowmobile starts. But once you’re out in the snow, your helmet begins to fog up, and suddenly, you’re not just battling the trails, but also struggling to maintain clear visibility. Over time, I’ve realized that keeping the helmet from fogging is as much a part of snowmobiling as the ride itself. So, let’s talk about it. Let’s discuss how to prevent our helmets from turning into a foggy mess so that we can enjoy the ride without any hiccups.

Why Does Snowmobile Helmet Fog Up?

Before we dive into solutions, it’s important to understand why snowmobile helmets fog up in the first place. The main culprit is a difference in temperature between your body and the outside environment. When you’re all bundled up with warm gear on, your body generates heat, causing moisture from sweat and breath to build up inside the helmet. Meanwhile, the cold air outside cools the outer shell of your helmet, creating a temperature difference and causing condensation to form on the inside of your visor. This can significantly impact visibility and make it difficult to navigate through the snow.

How Do I Keep My Helmet From Fogging Up?

Use Anti-Fog Products

The first way to prevent your helmet from fogging up is by using anti-fog products, such as sprays or wipes. These are easily available in the market. I have used some of them in the past, and they work pretty well. Once applied to the inside of your helmet visor, it creates a thin film that prevents the formation of condensation. However, it’s not a permanent solution as you’ll need to reapply it periodically. But, it’s a quick and inexpensive fix that can help you in a pinch.

Use Heated Shield

The heated shield is another great option to prevent fogging, and this is something I personally use for my rides. So, what is a heated shield? Well, it’s a visor that comes with a heating element running around the edges. It needs to be connected to the snowmobile’s electrical system. Once powered, it heats up enough to keep the temperature on the inside of the visor closer to the outer temperature, thus preventing the condensation responsible for fogging. It might seem a bit tricky to install, but trust me, it’s not that complicated. And the best part, once installed, you won’t have to worry about your helmet fogging up, no matter how cold it gets outside. If installing heating shield looks difficult to you, and you are looking for a new helmet, then you can purchase a helmet with built-in heated shield. You can read my review on Ski Doo Oxygen Helmet, it’s a great helmet with heated shield.

Ventilation is Key

Ventilation plays a vital role in preventing fogging. Many snowmobile helmets come with adjustable vents that let you control the airflow inside your helmet. When you’re riding, open these vents to let the warm air out and bring the cold air in. This can help to balance the temperature inside and outside the helmet, reducing the chance of fogging. It’s a simple thing, but trust me, it can make a big difference. It is also important to note that your snowmobile helmet should fit perfectly otherwise ventilation may not work.

Wear a Balaclava or Breath Deflector

Wearing a balaclava or a breath deflector can also help to prevent fogging. Balaclavas help by absorbing the moisture from your breath, while breath deflectors redirect your breath down and away from the visor. This reduces the amount of warm, moist air that comes into contact with the visor, ultimately preventing fogging.

How do you make anti-fog spray for helmets?

If you’re looking for a DIY solution to prevent fogging on your snowmobile helmet, here’s a simple recipe for making your own anti-fog spray:


  • Spray bottle
  • Distilled water
  • 70% isopropyl alcohol
  • Liquid soap (dish soap or baby shampoo works well)


  1. Fill the spray bottle with equal parts distilled water and 70% isopropyl alcohol.
  2. Add a few drops of liquid soap (no more than 1/4 teaspoon) to the mixture.
  3. Shake well to mix all the ingredients together.

To use, spray the mixture onto your helmet’s visor and wipe it clean with a soft cloth or microfiber towel. Make sure to cover the entire surface of the visor, including the edges and corners. Repeat this process every time before you go for a ride.
