How to Prevent Goggle Fog
Expert tips from the Headucators to keep your vision crystal clear on every run
Airflow = Anti-Fog
Fog is just warm, moist air trapped behind the lens. The solution? Give it a path out. Stack your vents, keep airways clear, and let physics do the work.
Quick Fix Flowchart
Fog at Top Edge
Open front sliders one notch and confirm vent alignment between your goggle and helmet
Fog at Bottom Edge
Check nose seal and strap tension and try low-bridge foam if seal is incomplete
Fog on Storm Days
Some fog is unavoidable but keep vents fully open and ensure facemask doesn't block breathing
Airflow Essentials
Stack the Vents
Line up goggle exhaust ports with helmet intake channels for maximum airflow
Open Smart
Crack helmet sliders on traverses and lift rides; close a click on wind-blown ridges
Don't Block It
Avoid mounting cameras or thick stickers over brim vents
Facemask Flubs: The #1 Fog Culprit
Above all else, make sure you leave room for air exhaust! Don't cover your nose or mouth with your facemask — warm breath needs somewhere to go, and if you block it, it's going straight into your goggles.
CLEARING THE FOG (TROUBLESHOOTING CHECKLIST)
-
Before anything else, confirm your ventilation system is fully open and your facemask sits below your nose and mouth—blocked airways are the most common culprit.
-
Top-edge haze usually means restricted upper airflow. Crack your helmet's front sliders one notch, double-check that goggle exhaust ports line up with helmet intake slots, and clear away any GoPro mounts or decals sitting over brim ventilation.
-
Bottom-edge condensation points to seal problems. Inspect how the foam meets your face around the nose, adjust strap tightness, and consider low-bridge foam inserts if gaps persist. Bulky beanies stuffed under the helmet liner can also break the perimeter seal.
-
Mid-session buildup often comes from changing conditions. Open vents during mellow traverses, dial them back a click on exposed chairlifts, and never rest goggles lens-down over your helmet's intake area. If moisture gets inside, let it evaporate naturally—dab gently with clean microfiber only.
-
Heavy weather creates a humidity cycle that's tough to beat entirely. Segmented face foam or quick-dry liner materials help. Stash a backup lens in an interior pocket where body heat keeps it warm and dry. If your lens touches the helmet brim when you tilt your head back, sizing down slightly or choosing a helmet with more brim clearance can reduce contact fogging.
-
The cardinal rule: never wipe the inner lens surface when it's damp. One swipe can strip the factory anti-fog treatment permanently, and no amount of troubleshooting will fully compensate after that.
