Thermal underwear

Men's military thermal underwear is a special type of clothing that helps maintain a comfortable body temperature under various conditions. The main properties of military thermal underwear are moisture removal, heat retention and dryness of the skin. Today, manufacturers offer various options for such underwear, which are used not only in military affairs, but also by athletes, outdoor enthusiasts and those who work with intense physical exertion.

Features of using thermal underwear

During heavy physical exertion, in the cold season or in the heat, the human body spends a lot of calories for thermoregulation. With improperly selected clothing or in extreme heat, the risk of overheating increases significantly, a lot of sweat is released, the body dehydrates and loses strength. In addition, the fabric becomes wet from sweat, becomes heavy and cools quickly. As a result, a person can even catch a cold. That is why military thermal underwear will be able to prevent all these phenomena and guarantee an optimal microclimate for the skin. In general, tactical thermal underwear provides the following features:

• Special viscosity and structure of fiber cells. Such properties of the fabric allow it to work efficiently to remove moisture. The sweat that is released enters the cells that are in contact with the skin, without lingering, and quickly rises to the surface. Then the moisture evaporates without harming the human body.

• Thermal insulation. Air is trapped between the small villi of the fabric, making it an ideal heat insulator. As a result, winter military thermal underwear retains the heat that the body releases, preventing the body from overheating.

• High-quality ventilation. Even the densest thermal clothing worn in winter has ventilation options. Thanks to this, the skin breathes freely and does not sweat.

Main types of thermal underwear

Manufacturers offer many options for such clothing, among which it is worth noting the most popular:

• Heat-saving military thermal underwear for men . This segment uses mainly natural materials in the form of cotton, animal wool, etc. However, such products are not effective during heavy sweating, and therefore they are best used during walks in the winter in a non-intensive mode, as well as for hunting or fishing.
• Military thermal underwear , moisture-absorbing. In this case, the products are made of fabrics that have 100% polyamide or polyester fibers in a special weave. Such military thermal underwear is ideal for intense physical activity - for athletes who run, play football, ski or snowboard.
• Combined military winter thermal underwear . The fabric in this case includes natural and synthetic fibers, which harmoniously combine the necessary functions of heat preservation and moisture absorption. Having several layers, such thermal underwear is the best option for many uses.

Materials for production

The most commonly used synthetic materials include the following:

• Elastane. This material has thin threads that stretch very well, keeping their shape. Manufacturers offer such thermal underwear for the military to buy with a high elasticity and soft fit to the body.

• Polyamide is the most popular material in this production sector. The fabric is lightweight and provides pleasant tactile sensations.

• Polyester - most often this material is used in combination with other fibers, which ensures quick moisture removal, reliable heat retention and a guarantee of a long service life.

Natural fibers, which are also added to the raw materials for the production of underwear, include cotton and animal wool. Cotton is used to make military summer thermal underwear , which provides easy breathing for the skin, and in combination with synthetics, provides quick drying of the product.

The most common wool used is from Merino sheep. It has an antibacterial effect and makes it possible to significantly insulate things. Silk is rarely found in products - only as a supplement to synthetic fabrics.

Rules for choosing thermal underwear

When deciding to buy military thermal underwear, it is important to determine the purpose of the clothing before purchasing. For active sports, you need to choose products that can wick away moisture to keep the body dry. For winter, it is recommended to choose products that wick away moisture and retain heat.

If you plan to stay outdoors for a long time without activity, then you will need heat-saving thermal underwear without the function of wicking away moisture. Underwear made of thin cotton fabrics is good for everyday wear.

As for choosing a size, it is desirable that when worn under tactical pants or fleece, the item fits snugly to the body and does not create any difficulties for movement. The seams should be flat and on the outside. During operation, military thermal underwear should not stretch, and during washing, it should not shed or deform.
