More than an upgrade—this is baselayer apparel reinvented.
Revolutionary Sweat Management
The fabric has a patented textile stitch which allows for exceptional sweat management, preventing it from remaining in contact with the skin.
Thanks to micro-cavities present in the mesh of the fabric itself, sweat is carried to the outside without being absorbed, promoting correct transpiration, keeping the skin fresh and dry even during efforts more intense.
Thermal Regulation of the Body
The ability of the fabric to keep the body dry is fundamental for efficient thermal regulation.
When the skin is wet, the cooling effect of sweat is lost, but with Carbon Underwear®, this is not a problem. Your body temperature is optimally managed, in both hot and cold conditions.
Goodbye Bad Smells
Thanks to the materials with which it is made and its textile structure, the Carbon Underwear® fabric is naturally antibacterial, helping to prevent the formation of bad bacteria odors.
In other fabrics, however, bacteria metabolize sweat, creating unpleasant odors that permanently adhere to the textile fibers. This happens because the bacteria create a biofilm on the fabrics which is very difficult to eliminate, even after several washes in the washing machine.
