Why do my ski goggles fog up?

Fogging happens when warm moisture from your face meets the cold lens. Solutions: never put goggles on your forehead (your heat fogs them), ensure vents are not blocked by helmet or hat, never wipe the inner lens (destroys anti-fog coating), and choose goggles with strong venting systems. An MFI face mask helps by redirecting breath away from the lens.

Should my ski goggles match my helmet brand?

Not necessarily, but helmet-goggle compatibility matters. The goggle should sit flush against the helmet with no gap (called gaper gap) at the forehead. Some brands design helmets and goggles as matched systems. Always try your goggles with your helmet before buying, or check manufacturer compatibility charts.
