Thermo Biotex cuffs The Thermo cuff is highly elastic, ensuring a perfect anatomical fit on the arm. It is made of BTX polypropylene fiber which guarantees thermal insulation while still guaranteeing breathability and the elimination of moisture from the skin, always leaving the skin dry, thus avoiding the sensation of cold and damp. Easily foldable and pocket-sized, they stay perfectly in place without creasing the joints. The elasticated thermal cuff is completely silicone-free, to avoid annoying irritation or any allergies. The Thermo stretch sleeve can be worn in periods where temperatures vary from -20 ° up to + 10 °. 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, choose the color and find out the day when you can wear it and do your training with a technical and performing product. The elasticated thermal cuff 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 rules for the care of the garment. The Thermo sleeve, thermal and elastic, allows you to stay with your arms dry and thermoregulated, not only during physical exertion, but also in moments of pause or rest. The Thermo cuff is light, comfortable and breathable. The effect you feel is that of a second skin and therefore one with your body. The stretch fabric (both in length and in width) with which the Thermo Sleeve is made is silicone-free and adapts to the shape of the body.
