4 signs of good thermal underwear

Winter makes you wear panties for two tights, a jacket for a sweater, a sweater for a shirt, a T-shirt under a shirt. Feeling like a cabbage, you could go out and not be afraid of frost. True, limited body movements made the very stay in the cold meaningless — neither turn around, nor bend over.

All problems ended with the advent of thermal underwear. Warming, subtle, not embarrassing. It remains only to choose.


Clothes should be natural — pleasant to the body, no allergies or irritations. But thermal underwear pursues other goals — to warm. Cotton pants also keep you warm, but if you sweat, you will feel the same moisture and coldness during your stay outside. Synthetics cannot do this, because they repel water.

There are many types of materials: polyester, polypropylene, tetron, microfiber. Polypropylene is the best — it has zero absorbency. Manufacturers sometimes add wool or cotton to artificial fabric — this is not a minus, but a more pleasant feeling to the body..

Double layer

The fabric for thermal underwear is not always smooth. There are options as with a waffle towel — a small air gap is created. From a design point of view, it is beautiful, from a practical point of view — it heats less.

Two-layer fabric is the best base for thermal underwear. Inside there is a polymer material — it breathes and removes moisture. The outer layer is a cellular structure that retains air, and this is additional thermal insulation.

The fabric itself looks mesh or ribbed. It can be too expensive for a winter walk, but for a ski resort it is the most appropriate.


Everything here is individual: for sports, for walking, for jogging. Professional sports thermal underwear can and should have additional advantages — high-quality material, linings, pads for articular places. The longer you spend time in the cold, active, the more moisture resistant the material should be.

For walking around the city, the most budget options are suitable, but not in quality — due to the lack of additional functions.


Good underwear does not hinder movement, fits in size, has no seams on the arms and sides. They are not needed there, and if they are, then you need to think about the quality of thermal underwear..

It is difficult to distinguish a fake, so check the seams in unnecessary places, inquire about the production of the material and make sure you trust the supplier. Specialized stores will offer more choice and are responsible for the brand, so there will be fewer mistakes..

Summing up:

thermal underwear looks like a second skin — it does not squeeze, but does not dangle;

seams from the outside and only where they cannot be avoided;

you don’t sweat or smell;

after washing, nothing stretches and does not fade.
