FOG ON
LENSES.
Why it happens, how to fix it — and the small habits that keep your vision clear all day.
WARM AIR.
COLD LENS.
Every time warm, moist air from your face meets a cold lens, condensation can start to build.
It gets worse when airflow is restricted, the goggles are damp, or snow blocks the ventilation. Even a good anti-fog system has its limits when moisture gets trapped inside.
WHAT CAUSES IT?
Wet snow or powder blocking the vents or foam.
A buff sitting too high and trapping warm air.
Getting too warm and building up moisture inside.
Storing your goggles damp instead of letting them dry.
Wiping or scratching the anti-fog coating inside the lens.
GOOD GEAR HELPS.
Karl Goggles use a dual-layer lens with anti-fog treatment, top and bottom ventilation and triple-layer face foam to help reduce moisture and temperature differences.
No system is perfect if moisture gets trapped inside. Once it's in, it needs to get out.
DON'T WIPE
THE INSIDE.
The inner anti-fog coating is delicate. Wiping a wet lens can spread moisture and damage the coating permanently.
GET CLEAR AGAIN.
You take a tumble in deep snow and suddenly the inside starts fogging. Here's what to do.
DON'T WIPE IT
Leave the inside of the lens untouched.
SHAKE OUT THE SNOW
Clear loose snow from the frame, foam and ventilation.
LET THEM BREATHE
Lift the goggles slightly for 20–30 seconds and let the warm, moist air escape.
SOAKED? DRY THEM.
If the foam is wet, head indoors and allow the frame and lens to air-dry completely.
SWITCH IF YOU CAN
Carrying an extra lens? Switch to a dry one and get back on the mountain.
