Goggles, a helmet, and the right layers underneath your jacket round out a setup — and each one has a spec that actually matters more than the marketing around it.
Goggle lens VLT explained
VLT (Visible Light Transmission) is the percentage of light a lens lets through, and it's the single most useful spec for choosing a goggle lens:
- Low VLT (roughly 0-25%): darker lenses for bright, sunny days — cuts glare off snow
- Mid VLT (25-60%): versatile, all-condition lenses — a good single-lens choice if you only own one
- High VLT (60%+): lighter lenses for flat light, overcast days, or night riding — lets in more light when there's less of it to work with
Many goggles now come with photochromic lenses that automatically adjust across a VLT range, or interchangeable lens systems so you can swap between a low and high VLT lens as conditions change through the day.
Helmet sizing and certification
A ski or snowboard helmet should fit snugly all the way around with no pressure points, sit level on your head (not tipped back), and not shift when you shake your head with the chin strap fastened. Measure your head circumference and check it against the manufacturer's size chart rather than guessing — helmet sizing varies enough between brands that "medium" from one brand can fit differently than another's.
Look for a real safety certification (ASTM F2040 is the standard for snow-sports helmets in the US) — this isn't marketing, it's a tested impact-protection standard, and it's worth confirming on any helmet before you buy it.
How to layer for skiing and snowboarding
A proper layering system has three parts, each doing a different job:
- Base layer: worn against your skin, its job is moving sweat away from your body, not warmth. Merino wool or synthetic performance fabric — never cotton, which stays wet and gets cold once damp.
- Mid layer: a fleece or insulated puffy that traps warm air — this is your primary insulation layer, and the one to add or remove as temperature changes through the day.
- Shell (jacket/pants): your outer, weatherproof layer — blocks wind and snow, and (if it's a true shell rather than insulated) lets you regulate warmth by adjusting what's underneath.
The most common layering mistake is over-insulating with a heavy mid layer under an already-insulated jacket — you end up sweating on the way up and then cold once that sweat sits against your skin. A shell + adjustable mid layer gives you more real control than one thick all-in-one layer.
Frequently asked questions
What VLT goggle lens should I get if I only own one?
A mid-range VLT lens (roughly 25-60%) or a photochromic lens that adjusts automatically is the most versatile single choice, handling most conditions reasonably well without being optimized for either extreme.
How should a ski helmet fit?
Snug all the way around with no pressure points, sitting level (not tipped back), and it shouldn't shift when you shake your head with the strap fastened. Always check against the actual brand's size chart — helmet sizing isn't standardized across manufacturers.
How many layers do I need for skiing?
Three: a moisture-wicking base layer (never cotton), an insulating mid layer, and a weatherproof shell. Add or remove the mid layer as temperature changes rather than relying on one heavy layer for everything.
