What should children wear under their winter jacket? A guide to layering in winter
Start with a soft base layer, add a mid layer as needed, and let the winter jacket protect against wind and cold. The right choice depends on the temperature, wind, dampness, activity, and how long the child will be outside.
Layering makes it easier to take a layer off or put one on during the day. It is often more practical than one very thick sweater.
How to dress your child in three layers
1. Base layer
The innermost layer should feel comfortable and help the child stay dry. A long-sleeved top, woolen underwear, or a soft undershirt can be a good starting point. Wool insulates well on cold days, while cotton should be changed if it becomes damp after play.
2. Mid layer
The mid layer is the layer you can adjust most easily. Choose, for example, fleece, knitwear, or thin wool. An active child often needs a lighter mid layer than a child sitting still in a stroller or going for a long walk.
3. Outer layer
The winter jacket should protect against the weather while leaving room for the layers underneath. When the jacket is not tight across the shoulders and arms, the child can move freely and the air layer between the clothes provides better insulation.

How to check whether your child is warm enough
Feel the child’s neck or upper back. The skin should feel comfortably warm and dry - not cold, clammy, or sweaty. Cold hands alone do not always mean that the whole body is cold.
Wet or damp clothes should be changed. Young children may have difficulty telling you that they are cold, and the Danish Health Authority recommends paying particular attention to young children in cold weather. Read the Danish Health Authority's advice on young children's time spent in the cold.
Wool, fleece or cotton?
-
Wool: warm and practical on cold days.
-
Fleece: a lightweight mid-layer that is easy to put on and take off.
-
Cotton: soft and comfortable, but should be changed if it gets wet.
Common mistakes to avoid
- The same amount of clothing every day, regardless of wind and activity.
- Too many thick layers under a tight-fitting jacket.
- Wet clothes after playing in the snow or rain.
- Judging warmth based only on the hands.

Frequently asked questions
Should children always wear fleece under their winter jacket?
No. On milder days or during active play, a long-sleeved top or a thin mid-layer may be enough.
How do I know if my child is wearing too many clothes?
If the child is sweaty or clammy around the neck or on the back, there are often too many or too warm layers.
Should there be room for several layers in the winter jacket?
Yes. The jacket should have room for a mid-layer without restricting the child's movement.
