The Secret Lies in the Fabric

The configuration of the fabric allows sweat to be effectively drawn away from the skin to the outer layer of the fabric.

This means:

  • the skin remains dry
  • the formation of bacteria and bad odors are eliminated
  • the garment dries quickly after washing


    Main Characteristics

     Maximum Breathability

     The patented SIXS weave and the polypropylene found in our fabric create a perfect combination. With a lower liquid absorption rate and a greater water vapor permeability than other textile fibres.

    Constant Thermo Insulation

    Thanks to its blend of textile fibres, the Carbon Underwear® fabric is just like a breathable barrier that keeps the body temperature constant under all weather conditions.

    Fast Drying

     The fabric does not absorb sweat, but rather carries it to the outside so that the skin is left dry. The garments dry quickly after being washed.

    Light as a Feather 

    The Carbon Underwear® fabric has the lowest specific weight of all textile fibers on the market.


    Because of its conductivity, the fiber absorbs and disperses electric charges accumulated from the environment or during physical exercise.


    Because it respects the skin and protects it from bacteria and pollutant dusts: the Carbon Underwear® fabric has properties that eliminate the risk of annoying allergies, reduce the proliferation of bacteria and the procreation of bad smells.
