Wind and what it does to the layers

Short answer: Wind strips away the warm layer of air between skin and fabric. Without it, clothes insulate far less, and the same layers suddenly feel inadequate, so a tight outer layer does more than one more layer underneath.

The wind blows the warmth away

It is not the fabric that keeps you warm, but the air inside it, and the wind takes that air. Your body warms a thin layer of air between skin and clothes, and that layer is what keeps you warm. When wind pushes through, warm air is constantly replaced by cold. See bamboo hoodie for women.

Why you feel colder in the wind

A day of eight degrees and no wind can feel pleasant. The same eight degrees in a strong wind feels much colder. The thermometer shows the same, but your clothes are working under very different conditions. That is why yesterday's clothes suddenly are not enough today.

A tight outer layer solves most of it

A layer that stops the wind makes the other layers many times more effective. It does not need to be thick. It just has to keep air from passing through, so the warm air underneath can stay. See all women's clothing for soft layers to wear underneath.

Open knits are worst in wind

A loosely knitted layer lets the wind pass straight through. It feels thick and warm indoors, but in the wind it barely insulates. Use it as a middle layer under something tight instead. See most popular for women for the pieces most often worn in layers.

Closed openings keep the warmth in

The wind finds its way in wherever your clothes are open. The neck, wrists and waist are the usual spots. A layer with ribbed cuffs and hem seals better than loose edges. A hood you can pull up protects your neck when the wind is at its strongest.

The order matters

The soft layer belongs inside and the tight one outside. Turn it around, and the wind gets hold of the soft layer while the tight one just traps cold air. Think of your layers as a system where each one has its own job.

Be ready to adjust

The wind can pick up and die down over a day. An outer layer that is easy to take on and off makes adjusting simple. In a sheltered spot you can open it, and close it again when you step back into the open.

What you can do today

Check the wind speed in the forecast, not just the temperature. If it is windy, choose a tight outer layer over an extra thick one. Close the openings and bring a hood or scarf. Small choices make a big difference on a windy day.

Frequently asked questions

Why do you feel colder in the wind

Because the wind removes the warm layer of air between skin and fabric. Without it, your clothes insulate much less, even though they are the same clothes as yesterday.

What helps most against wind

A tight outer layer. It does not need to be thick, it just has to stop air from passing through, so the warmth underneath stays put.

Is a thick loose knit good in the wind

No. The wind goes straight through an open knit, so the layer barely insulates in the wind. Wear it under a tight outer layer instead.
