Frequently asked questions
What VLT should ski goggles have for storm days?
For storm days with heavy snowfall and overcast skies, look for a VLT (visible light transmission) of 50–80%. This range lets enough light through to help your eyes define terrain features in flat, gray conditions. Lenses under 40% VLT — common on all-mountain 'versatile' lenses — will feel dark and make storm skiing genuinely dangerous.
How do I keep my ski goggles from fogging in heavy snow?
The most reliable defense against fogging is a dual-pane thermal lens with an anti-fog inner coating — it works passively without batteries. Beyond that, resist the urge to wipe the inside of your lens with your glove (it destroys the anti-fog coating). Ensure your goggles have top vents with baffles, and make sure your helmet isn't blocking airflow to those vents. Heated goggle systems like certain Smith lenses offer the best fog protection but cost significantly more.
Can I use flat-light goggles for storm skiing?
Low-light and storm lenses overlap significantly — both need high VLT. The key difference is storm conditions add moisture and blowing snow, so you also need a robust seal, strong ventilation, and ideally a dual-pane lens. A goggle designed purely for flat light in dry conditions might have thinner face foam or less aggressive venting that struggles in active precipitation.
Do I need a separate storm lens or is an all-condition lens good enough?
Many top-tier goggles include only one lens, and a high-quality all-condition lens (VLT around 40–60%) performs reasonably well across conditions. But if you ski frequently in actual storms or true whiteouts, a dedicated storm lens in the 60–80% VLT range makes a noticeable difference in contrast and depth perception. Quick-change magnetic systems from Smith and Anon make carrying a second lens practical.
Are heated ski goggles worth it for storm days?
Heated goggle lenses — which use a thin electrical element to keep the inner pane warm and prevent condensation — are effective and basically eliminate fogging, but they add weight, require charging, and carry a significant price premium. For most recreational skiers, a quality dual-pane goggle with good ventilation is sufficient. If you guide, ski patrol, or spend full days in sustained heavy snowfall, heated tech is worth serious consideration.
