It can then come to biological processes, such as bacterial growth, fungus or mold. In addition, the air exchange is no longer sufficiently ensured, so that sweat accumulates between the skin and the fabric, which reduces the comfort and can cause cold to the wearer.
  • Down also known as lower springs, are feathers with short keel and soft feathered branches. Down is used in textile products, such as jackets, bedding or sleeping bags, as thermal insulation fillers. The downs are contained and enclosed in sheaths of flat textile structures.
