Hiking in the snow is not simply a matter of adding a heavy jacket. Climbing generates heat, while wind, moisture and rest stops can cool you down very quickly. Your clothing therefore needs to adapt throughout the outing.
The short answer: wear a breathable base layer, adjustable insulation and an outer layer to protect against wind and moisture. Give your extremities extra protection and keep a warm layer within easy reach for breaks.
Manage moisture first
In snowy conditions, perspiration quickly becomes uncomfortable if it stays next to your skin. A breathable base layer helps manage this moisture; add an insulating layer according to your activity level and remove it if you get too warm on the climb. The aim is to stay dry before trying to stay very warm.
Protect against wind and snow
An outer layer becomes essential in wind, spray or wet snow. A hardshell protects your layering system; it does not replace insulation. Check that the fit leaves enough room for a fleece or lightweight down jacket.
Do not under-estimate breaks
The perceived temperature drops as soon as you stop, particularly on a ridge or summit. Keep a warm layer easily accessible in your pack and put it on before you feel cold. Gloves, a beanie and neck protection also make a crucial difference.
A typical outfit
- On the climb: a breathable base layer, flexible trousers or softshell trousers depending on conditions, and a lightweight layer if needed.
- During breaks: a fleece or down jacket, warm accessories and wind protection.
- If the weather deteriorates: a hardshell jacket and trousers depending on moisture levels and exposure.
Adapt to the terrain
A snowy woodland walk and an alpine outing do not require the same safety margin. Carry more insulation as altitude, duration, wind exposure and the difficulty of a quick return increase.

In summary
For hiking in the snow, set off with an adaptable layering system: wick away moisture on the climb, add insulation when you stop and protect the whole system as soon as wind or moisture sets in.
