Polypropylene is considered an ideal material for the manufacture of such clothes, since it does not absorb moisture at all. To make such underwear more pleasant to the body, a little wool or cotton is added to it.



To achieve a thermal effect, manufacturers use two methods of weaving fiber:

  • Weaving in a longitudinal hem or mesh. It is used when using polymeric materials.
  • Waffle weaving. This technology implies a thick air gap, due to which the linen heats perfectly, but moisture is not removed well enough.

So, the inner layer is made of polymer fabrics, but the outer layer has a structure consisting of cells, which actually provides good thermal insulation, the fastest evaporation and a good distribution of moisture. You can get rid of the unpleasant odor after prolonged wear with the help of special antibacterial agents.
