The long sleeve base layer Biotex 3D is truly made in 3D, in fact, besides the dimensions of width and height, there is also the third dimension: the relief, its depth. Its insulating and thermal power is enhanced by the 3D Capture processing, which reduces the contact surface between skin and fabric, promoting climate regulation thanks to the unique structure of the fibers that store air in 'bubbles' inside, thus preventing the annoying sensation of the fabric sticking to the skin. The long sleeve 3D turtleneck is a long sleeve turtleneck that is based on an innovative processing technique, which creates a particular visual effect. The garment features an excellent fit and optimal moisture management, like every base layer produced by Biotex. To optimize sweat channeling and keep the skin warm and dry, the 3D turtleneck has been made with an internal honeycomb structure that retains body heat and an external 3D structure that enhances its insulating and thermal power because it reduces the contact surface between skin and fabric, promoting climate regulation thanks to the unique structure of the fibers that store air in 'bubbles' inside, thus preventing the annoying sensation of the fabric sticking to the skin. With a snug and comfortable fit, the 3D turtleneck is lightweight, yet it protects the body from cooling while keeping it dry and ready for maximum performance. Among men's turtleneck shirts, the 3D turtleneck has been chosen by various professional teams as winter base layer. You can wear the long sleeve 3D turtleneck as the first layer in contact with the skin (paired with other more or less technical garments) in periods where temperatures range from -5C to 15C. The temperature range indicates the extreme limits of use. Therefore, the center of gravity of the temperatures should be evaluated as a reference to meet your needs, which vary based on the sport, climatic conditions, and your thermoregulation. To increase thermal effectiveness and protection, it is recommended to combine multiple technical layers, as per Biotex philosophy. Check which size is suitable for you based on your body characteristics, choose the color, and discover the day you can wear it and do your training with a thermal, technical, and high-performance base layer product. The long sleeve turtleneck base layer is guaranteed by Biotex's experience. The garment does not lose its technical qualities over the years nor after many washes: it is important to follow some simple washing and care rules.
