DO NOT RUB INNER LENS SURFACE WHEN WET
Sound ridiculous? Unfortunately it’s very true, by rubbing the inside of a ski goggle when it’s wet (has snow inside the goggle!) you will smudge the anti fog layer. Eventually this will make the ski goggle completely unusable.
Shake any excess snow from the interior of the goggle
Use the microfiber bag that was supplied with your ski goggles to gently blot out any remaining moisture.
Allow time for the remaining moisture to dry out and once wearing again keep moving to allow airflow to finish drying the inside of the goggles and bring them back up to their full anti-fog.
