Suitable technical underwear for sport can be recognised by its specific characteristics:
- it conveys all the humidity outwards;
- it is thermal and maintains body heat during the winter months;
- it keeps the body dry and cool during the summer months;
- it is hypoallergenic and antibacterial.
In order to obtain a garment with such qualities, it is certainly necessary to know about and understand the applications of innovative materials, woven with a special texture, that only those, like BIOTEX, who have done their job and continue doing research and making innovations, are capable of offering.


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.
