The Biotex Calore long sleeve base layer in extra-fine Merino wool is a soft and warm technical garment. In contact with the skin there is polypropylene (our BTX fiber) which offers the dry effect and transpires sweat, dissipating it quickly. This shirt has a collar that is just over 4 cm high which protects without annoying. The comfortable raglan cut of the sleeves and the seamless "seamless" technology make this thermal underwear a garment suitable not only for cycling but also for all outdoor winter sports. Ensures freedom of movement and excellent comfort on the skin (does not pinch!). The shirt weighs only 140 gr. but it releases a heating power almost double its weight. You can wear the Turtleneck sweater as the first layer in contact with the skin (combined with other more or less technical garments) in periods when temperatures vary from -10 to 15 . The temperature range indicates the extreme limits of use. Therefore, the center of gravity of temperatures must be evaluated as a reference to meet your needs which vary according to sport, climatic conditions and your own thermoregulation. To increase thermal and protective efficacy, the combination of several technical layers is recommended, as per the Biotex philosophy. Check which size is right for you based on your body characteristics and find out the day when you can wear it and do your workout with a thermal, technical and performing underwear product. The long-sleeved underwear shirt is guaranteed by the Biotex experience. The garment does not lose its technical qualities either over the years or after many washes: the important thing is to follow some simple washing and care rules for the garment.
