If properly cared for, you will be able to use your Biotex underwear for a long time. Biotex uses textiles created especially to be in contact with the skin. To prolong the special characteristics, it is advisable to wash your Biotex garments on a delicate cycle at a maximum temperature of 40° and then air dry them. If these recommendations are not followed, we cannot ensure the effectiveness of the garments. They must absolutely never be ironed.
