Thermal clothing: how to stay warm in winter
Cold mornings on the bike, a winter walk, an evening at the Christmas market or a week on the slopes: in winter you want to be warm without having to put on ten layers. Thermal clothing helps with that. In this article you will read how it works and how to keep your hands, feet and head warm too.

What is thermal clothing?
Thermal clothing, also called thermal underwear, is a thin layer you wear directly against your skin. It holds a layer of warm air around your body and wicks moisture away. That keeps you warm, even when you move and sweat a little.
Why not cotton?
A cotton T-shirt absorbs a lot of moisture and dries slowly. If you sweat, that wet layer stays against your skin and you actually get cold. Thermal clothing is made to carry moisture away from your skin.
The layering principle
- Base layer: thermal clothing against your skin
- Mid layer: a fleece or jumper that holds in warmth
- Outer layer: a jacket that keeps out wind and rain
That way you can easily take a layer off when you get warm, for example when you come indoors or walk briskly.
What to look for
- Fit: thermal clothing should fit closely, but not pinch. Too loose and it works less well.
- Top and bottoms: for winter sports and long trips you wear both. For everyday use a top is often enough.
- Washing: follow the care label and do not use fabric softener.
The Travelhawk Thermal Clothing is a black thermal base layer for men and women.
Warm hands, feet and head
You lose heat quickly through your hands, feet and head. These items keep them warm:
- Touchscreen gloves: use your phone without taking your gloves off.
- Waterproof gloves: for rain, snow and wet bike rides.
- Ski socks: warm socks, also welcome on cold winter days off the slopes.
- Winter hat, neck warmer or balaclava: against cold wind on your head and neck.

Extra tips against the cold
- Do not lace your shoes too tightly: good circulation keeps your feet warmer.
- Wear two thin layers rather than one thick one.
- Take a vacuum flask with something warm on a winter walk.
- At home on the sofa: a fleece blanket and a hot water bottle make it cosy straight away.
Frequently asked questions
How does thermal clothing work?
Thermal clothing fits close to your skin, holds a layer of warm air and wicks moisture away. That keeps you warm and dry.
Do you wear anything under thermal clothing?
No, thermal clothing goes directly against your skin. Only your ordinary underwear goes beneath it.
Should thermal clothing be tight?
Thermal clothing should fit closely, but not pinch. That is how it wicks moisture best.
Can I wear thermal clothing in everyday life too?
Yes, for example on the bike, during a winter walk, for outdoor sports or at the Christmas market.
