Species and their purpose
Thermal underwear is a specialized clothing that accumulates the heat of the human body. Unlike ordinary, warm linen, it also has the property of removing moisture. These are clothes in which it is equally comfortable outdoors and indoors.
Thermal underwear is a common name for warm underwear.
Thermal underwear is produced in the form of:
- Socks - they look like ordinary socks, but their main function is to absorb moisture that the skin secretes. The skin remains dry, and the risk of freezing of the legs is minimized. Normal sweating does not allow the feet to overheat. And thermal socks are great to save from the formation of calluses;

- Underwear is a warm and comfortable alternative to the usual panties and sconces. Both special kits for active sports and sets for everyday wear are sewn;

- Leggings or tights - thin and versatile leggings are indispensable for girls in the winter season. This item of clothing is worn instead of tights, and on cold days it is worn under jeans or trousers;

- T-shirts or longsleeves - suitable for wearing as the first layer of clothing, and in especially cold times are worn under hoodies and hoodies;


- Suits are the most popular type for outdoor activities, sports and everyday wear. A set of leggings and a long-sleeved top is worn, for example, under jeans and sweaters.

Also, thermal underwear is divided into groups by activity:
- Heat-saving – this species is for low and medium activity and cold climates. Underwear helps to warm up due to the increased air gap between the body and clothing. The air is heated to a comfortable temperature and does not allow a person to freeze. Heat-saving underwear is suitable for low activity, for example, winter fishing, a leisurely walk or an overnight stay in a sleeping bag;


- Moisture-excreting - designed to remove moisture from the surface of the skin and maintain the body in a comfortable temperature. Thermal underwear is made of synthetic materials that do not absorb liquid. Heated air comes out through the fabric, sweat does not remain on the clothes, but evaporates. Moisture-wicking underwear is necessary for high activity, for example, running, when a large amount of sweat is released;


- Hybrid - such underwear combines the qualities of heat-saving and moisture-removing thermal underwear. Manufacturers strive to maintain a balance of functions due to dual layering. The inner synthetic layer removes moisture, and the outer one retains heat. Hybrid thermal underwear is used for periodic changes of active and calm activity.

Selection of the right material
The fabric is chosen depending on the needs and activity, so it is important to understand whether you choose thermal underwear for sports or rather for everyday wear.
Types of fabrics used for sewing thermal underwear:
- Wool - it does not prickle, and it is also the material with the lowest thermal conductivity. The main feature of wool is the preservation of heat-shielding properties even when absorbing water up to 30% of body weight;

- Synthetics – A mixture of artificial fibers is commonly used. This can be, for example, nylon, polyester and elastane;

- Silk is a smooth, pleasant to the touch and hypoallergenic fabric. It is ideal as a base layer to protect the body from the cold. But it is important to pay attention only to silk of dense and heavy knitting;

- Cotton is natural, but for thermal underwear it is not the best option, because it gets wet even at low body humidity and becomes ineffective;

- Footer with a comb is a warm and wear-resistant fabric, but fastidious in care and washing. Of the pluses can be identified low electrification;
- Fleece is a soft hypoallergenic material. Retains heat well, but is highly electrified;

The main parameters that should be considered when buying:
- The material with which the skin comes into contact should be soft and pleasant to the touch. In this matter, it is better to choose a fabric with flat seams;

- For winter long walks, choose two-layer materials, which include wool. It will provide heat and increase the intensity of blood circulation in the skin capillaries. Alternatively, merino wool;

- If you choose thermal underwear for sports, do not be afraid of the presence of synthetics, since synthetic materials are responsible for excess moisture. It is important that the structure of thermal underwear is porous. An excellent choice is polyester or polypropylene, possibly with the addition of natural fibers.

How to choose the right size?
It is important to choose thermal underwear so that it sits well and does not cause discomfort in the sock and there are certain rules for selecting the size of thermal underwear:
- Choose a model that fits the skin and clearly matches your size. Nothing should hang, otherwise the thermal underwear will not work properly;

- When selecting, do not focus only on the dimensions written on the label. It is better not to be lazy and put on your underwear to make sure that the clothes sit comfortably both in static and in motion;

- Pay attention even to small details. Sutures should not interfere and prick, and the fabric should tighten the skin. Cuffs on the sleeves and pants pick up elastic, so as not to press and not to crash.

Rules for wearing thermal underwear
- Thermal underwear is worn exclusively on a naked body, otherwise there will not be a good effect, so even for thermo-longsleeve you do not need to wear a T-shirt or ordinary underwear under the bottom. Shorts should also not be worn over regular panties;

- Do not wear thermal underwear all the time. At home, it is better to change into clothes made of more natural fabrics, since synthetics absorb moisture too much and you can overdry the skin;

- Combine thermal underwear with suitable outerwear, relying on temperature. If you use thermal underwear in everyday life and do not want to freeze, add another 10-15 ° C to the limit specified in the temperature characteristics;

- To feel as comfortable as possible, each subsequent layer should be wider, more voluminous, because the body retains the temperature by heating the air between the layers. Therefore, multilayering is used - for example, the base, middle and outer layers.
