How to choose the right thermal underwear?

Thermal underwear works on a very simple principle. In the manufacture of thermal underwear a special fabric is used (more often synthetic, with special weaving), which has unique properties (moisture removal and thermal insulation). Therefore, when a person naturally heats a certain layer of air between the skin and the laundry, the thermal underwear does not let the heat escape and hold it. In turn, the sweat produced by the body as a result of physical activity is not absorbed by the tissue, but is removed from the surface of the skin and evaporates without the man's expenditure on it energy and heat loss. In this case, ordinary underwear absorbs moisture, contributing to hypothermia, and thermal underwear leads it outward, while retaining thermal insulation properties.

Advantages of thermal underwear countless, so it's no surprise that its popularity is so high. A wide selection of this product can be found on the price comparison site http://priceok.ru/termobele/cid9723, as well as compare the prices for the model you like.

What you need to know about choosing a thermal underwear?

The first factor by which this clothing is chosen is the material. There are a lot of materials, manufacturers use new technologies to satisfy the demand of each buyer. How to choose a thermal underwear for different occasions?

Material

1. Cotton. Natural material that is better used for everyday wear, walks in frosty weather, for winter fishing, and also for sleeping. The material takes moisture out well, providing a stable thermal insulation effect. But, if the underwear completely gets wet, moisture will be held near the body. For this reason, cotton thermal underwear is not suitable for sports training.
2. Wool. Expensive thermal underwear is made on the basis of merino wool, but you can meet other types of material. Wool not only retains heat, but also provides a warming effect. Wool thermal underwear suitable for long walks, as well as for those people whose work is associated with a long stay in the open air.
3. Synthetics. Polypropylene and polyamide are the two most common materials used for the production of synthetic thermal underwear. Quickly remove moisture, do not accumulate odors, do not crumple, keep shape, wear-resistant. Special antibacterial impregnations are often used. Polypropylene is used for the production of sports thermal underwear, it can not be worn for long, like sleeping in it, as the material dries the skin (it fits snugly to the body and can cause itching). But for training in winter weather is the best option. Sometimes synthetics are "diluted" with natural wool to improve thermal insulation properties.

And yet: synthetics or natural fabrics? A natural cloth is suitable if your goal is a long walk and a long stay outdoors at low temperatures. Natural material will fulfill its main task - warming. If your goal is active training, only synthetics will cope with the main task - the removal of moisture. During training, the body sweats, and if the moisture will linger, then during rest the body will begin to supercool.

How should thermal underwear sit on the body? Anyone who does not like tight clothes should understand that free thermal underwear will not have absolutely no effect, because air layers between the body and the fabric, due to which the thermo-insulating properties are achieved, simply will not be. Very often you can come across a notion such as "second skin", which describes the principle of wearing thermal underwear. It is better to purchase a smaller size than the larger one. Thermal underwear should fit tightly the body, avoiding the gaps between the skin and the tissue.

It is also important to choose the right models for the winter and summer period, which differ in the thickness of the fabric (super-light and light fabric - for the summer, medium and warm - for the autumn-winter period).

Companies that produce thermal underwear, quite a lot, both in our country and abroad. Among the brands that have a good reputation, MJ Sport, VAUDE, Marmot, Helly Hansen, MILLET, LOWE ALPINE, Craft. This is a list of companies from Europe and the USA. As for domestic producers, Bask and RedFox will be a good option.

The choice of thermal underwear depends on the conditions of use: if you often practice walking, your choice is thermal underwear made of wool and cotton, if you are an athlete, it is better to buy synthetic underwear, perhaps with the addition of natural fabrics, if you want to get a model for everyday wear - natural wool to help you.

Correctly selected thermal underwear will protect from moisture, wind and will not irritate the skin. The only drawback of thermal underwear is its lack of versatility, as different types of clothes are required for different conditions. But, having defined, in what conditions you happen more often, this minus comes to naught.
