Ski goggles fog when warm, moist air from breathing or sweating condenses on a cold lens surface. This often happens during high-output skiing, when wearing a face covering, or in warmer, humid conditions. Even high-quality goggles can fog if moisture and airflow aren’t managed effectively.

How to prevent ski goggles from fogging while skiing

• Avoid overdressing – Excess heat and sweat increase moisture inside the goggles
• Position face coverings carefully – Keep warm breath from rising directly into the lens
• Let goggles dry fully between runs – Trapped moisture makes fogging worse
• Keep vents unobstructed – Blocked airflow prevents moist air from escaping
• Handle the inner lens gently – Rubbing or wiping the inside can damage anti-fog coatings over time

While anti-fog coatings help, they can wear down with use and improper cleaning. That’s why many skiers look for goggle designs that actively manage moisture and airflow, rather than relying on coatings alone to keep lenses clear.

What anti-fog solution is best for you?
The best anti-fog ski goggles depend on how and where you ski. High-output skiing, humid weather, storm days, and frequent temperature changes benefit from more aggressive fog management. More relaxed resort skiing in dry, cold conditions may require less intensive solutions. Choosing goggles designed for your typical conditions can help keep your vision clear throughout the day—without stopping to wipe or defog your lens.
