Thermo + Turtleneck Base Layer

You can wear the HEAT turtleneck base layer in contact with the skin (combined with other technical garments) on days when temperatures range from -20° to +10°. We recommend wearing this garment when temperature is within the range specified above. But to decide what will meet your needs, which will vary depending on the sport, the climatic conditions and your own temperature regulation, you should evaluate what is the average temperature that you will encounter. In order to increase the effectiveness of its thermal and protective properties, we recommend wearing several technical layers in combination, in line with Biotex philosophy. Check which is the right size for you based on your body characteristics, choose the colour and find out when is the ideal time to wear this high performance technical thermal underwear product for your training. This long-sleeved base layer is guaranteed by Biotex's experience. This garment will retain its technical qualities over the years even after frequent washing but it is important to follow some simple rules for washing and caring for it.

For over 20 years we at Biotex have been producing technical underwear to improve sports performance. We were the first Italian company to experiment with and use polypropylene in our products, a material that ensures breathability, lightness and constant body temperature regulation. We are also Partners of professional sports teams with whom we test the effectiveness of our technical apparel in the field in order to perfect it and make it perform well in every kind of sport.

Take care of your Biotex garments and they will last for a long time. Biotex uses fabrics specially created to be in contact with the skin. To maintain their characteristics, we recommend gentle washing at a maximum temperature of 40° and air drying. Otherwise, we cannot guarantee the garment's effectiveness. They must never be ironed. These fluorescent socks may fade after several washes.
