Thermal underwear: functions, choice and care rules

When there is a minus temperature on the thermometer outside the window, and you are not accustomed to hiding from frosts, it's time to think about warming your body. You can wear a hundred warm clothes and look like a cabbage in a hundred clothes. We offer a different method. Meet the thermal underwear! Thanks to such clothes, we will not have to pull on our entire warm wardrobe, but about everything in order. So, thermal underwear. Many immediately thought of linen, which should warm our body. This is a somewhat misconception about thermal underwear. First of all, thermal underwear is a functional underwear that is capable of removing the moisture collected on the body and thereby preserving heat.

Polypropylene, polyester, cotton, wool and other types of fabrics are used for manufacturing thermal underwear. Synthetic lingerie is more durable, it dries quickly, and very well removes moisture. Linen with the addition of cotton or wool adds a sense of comfort when wearing.

Thermal underwear can be worn not only for sports, but every day. Especially actual thermal underwear for those who engage in extreme sports: kayaking, rafting, etc. Even in the summer, some athletes wear thermal underwear, in this case it is best to choose a thermal underwear made of synthetic fabrics, because linen will retain its properties longer.

Fans of snowboarding and downhill skiing should choose synthetic thermal underwear or underwear with the addition of cotton or wool. In this case, the laundry is able to fully perform its functions, about 3 to 8 hours, after this time, the laundry stops performing its "work".

As for thermal underwear for every day, in this case, it is best to choose linen, which includes wool or cotton. In winter it is best to choose models from heavy materials, but in the summer from more subtle.

Thermal underwear and its functions
There are two such functions: the first is a warming function, and the second is to remove moisture, the third function is a combination of the first and the second. When you wear ordinary underwear and do physical labor, moisture accumulates in the laundry, while the thermal insulation properties of the laundry decrease. The organism additionally has to expend energy in addition to warm the body, and also to evaporate the moisture. Thermal underwear made of polypropylene does not absorb moisture, water simply drains, while the laundry dries quickly on the body. Functional underwear in the cold season reduces heat loss, while there is a feeling of comfort.

The operating principle of thermal underwear is as follows. The material of thermal underwear has a loose volumetric structure, due to which the heat of the body is retained, which means that the person does not face hypothermia. The thicker the fabric of thermal underwear, the more air it can hold in it, which means it will be better to heat.

For winter hikes, mountaineering or freeride, it is best to choose a linen of combined functionality. This laundry is made of two layers: the outer layer is the heat of the saving and the inner layer is the moisture separating layer. Depending on the manufacturer, the thickness of the thermal underwear can be different.

Choosing thermal underwear
Choose a thermal underwear depending on the physical activities and sport. For skiing, experts recommend choosing linen with combined properties. But for hiking in the cold, it is worth paying attention to warming underwear. Pay attention to the fact that the thermal underwear must necessarily fit snugly to the body, but do not constrain movement.

To feel how the thermal underwear works, when dressing it is necessary to adhere to the principle of 3 layers: first the thermal underwear, then the insulating layer and at the end the protective layer (suit, trousers, jacket). Adhering to the three-layer principle in clothes, it is worth remembering that each layer must breathe, otherwise the thermal underwear will work like ordinary body clothes.

Rules of care for thermal underwear
Washing can be done both by hands and in a washing machine at t no more than 40 ° C. When washing thermal underwear at higher temperatures, the material from which the thermal underwear is made permanently loses its warming properties. When washing in the car, you must select a gentle wash with antistatic rinsing. It is better to refuse spin, but to allow the water to drain, and to drain naturally without using batteries or any other heating devices.

It is extremely undesirable to dry the thermal underwear in the drying chamber, as well as ironing and boiling of the laundry is prohibited.
