X-Bionic Fennec 4.0 Headband With Visor

Technologies and manufacturing processes

• 3D Bionic Sphere® System

  The body sweats during activities. The natural cooling system keeps the body at an ideal 37°C by means of sweat. Traditional thermal underwear draws the cooling sweat away from the skin. This tempts the body to produce even more sweat. Valuable fluids, minerals and salts are lost without efficient cooling. This reduces performance.
  Cools when you sweat. Warms when you're cold.
  The award-winning 3D Bionic Sphere® System stops unpleasant moisture, the feeling of overheating during rigorous activity and prevents cooling during rest and recovery phases.

• Fennec® Technology

  Burning sun, shiny black asphalt or heated house facades are environmental factors that heat you up during sporting activity. By regulating your body temperature, you lose valuable energy.
  Running and biking like in the shade.
  The basis of the X-BIONIC® desert fox technology is the unique material XITANIT®, which reflects radiated heat and widely distributes sweat across the skin, to provide effective cooling. At the same time, the conductivity of the bacteriostatic yarn draws excess heat from the body and dissipates it in the outside air.
