What Causes Ski Goggles To Fog Up?
In a word: condensation. As the air inside your ski goggles is warmer (due to your body heat) than the outside air, condensation will form inside your goggles. And just like your car windscreen on a cold night, that leads to fogging.
How To Prevent Fogging
Before covering defogging your ski goggles, here are 3 ways that you can help to prevent them fogging up in the first place. Prevention is better than cure right?
1: Keep Your Goggles Dry
When your goggles are moist (due to sweat, or snow), the humidity inside the lenses will increase. The higher the humidity inside your goggles, the more chance that you’ll get fog. So keep your goggles as dry as possible.
2. Keep Your Vents Clear
Most ski goggles have vents, which help to regulate the temperature of the air inside. If your vents are clogged up, they can’t do their job and you’ll be much more likely to get fogging.
3. Don’t Block Your Vents With Clothing
Staying on vents, they can also get blocked by clothing such as scarves and hats. So make sure you keep you clothing a couple of inches away from the vents. No point clearing them only to block them again with your scarf!

Time To Upgrade Your Goggles?
If you’re having big trouble with your goggles fogging up, it might be worth upgrading to a pair with a larger interior volume. Why? Because more internal air, means more time for that air to heat up.
