Base Layer Sets

This category of clothing includes thermoactive sets, which are the first, basic layer of clothing. We recommend it especially to those who practice sports and tourism, it will also be appreciated by uniformed service workers, escorts and security personnel. It is indispensable during service in the field and during maneuvers on the training ground. The most important task of this type of underwear is to wick moisture away from the body. This is important because during physical exertion, such as in sports or tourism, we often have to deal with cold or wind, which can quickly lead to hypothermia. This, of course, has its consequences, we can catch a cold or even, in extreme cases, lead to hypothermia.

Unlike cotton, which soaks up and takes a long time to dry out, the materials that are the basis of thermoactive sets transport sweat to the next layers of clothing and then to the outside. Thus, they make sure that it does not come into contact with the skin and does not take away our precious body heat. The second important factor is thermal insulation. Depending on the prevailing weather conditions, we naturally choose the right type of underwear. When it's cold we choose such thermoactive sets, which, thanks to being made of the right fibers and the right thickness, additionally warm up our body. Then, when it is warmer or when the exertion will be greater, we must decide on the right balance between heating and the speed of transport of moisture to the outside. On hot days, we choose a version of underwear that will be the thinnest and at the same time provide the greatest vapor permeability (breathability).

In our store we have a wide selection of thermal underwear from reputable manufacturers such as Columbia or Under Armour. You will also easily find Polish brands with us, such as 4F or Freenord.
