Targeted Increase of the Evaporation Surface

The 3D-BionicSphere® System, efficiently positioned on the chest, works without the sensation of wetness or heat and no risk of overcooling during recovery.

The cooling is activated only when the body‘s temperature rises and sweating begins. If no sweat is present, then the system serves as insulation. The 3D-BionicSphere® System only begins to cool once you are sweating. During the event sweat forms a fine film of moisture on the skin. Drops are absorbed by the SweatTraps™ and conducted into the Evaporation Surface Expander™. The evaporation, activated by body heat, occurs in 3 ways:

  • On the skin, for cooling.
  • In the SweatTraps™, to process excess moisture
  • In the Evaporation Surface Expander™, where the excess is finally evaporated.


are channels that store air in the interior of the 3D-BionicSphere® System. Their surface lies up to 5 mm from the skin and from there leads into the Evaporation Surface Expander™.


These channels deliver fresh air into the 3D-BionicSphere® System, ventilating the SweatTraps™. The air which, is warmed here, quickly becomes saturated with moisture and is replaced continuously by the subsequent flow of cold, fresh air; the ventilation circulates actively for as long as the body continues to sweat. Evaporation Surface Expander™ can absorb and evaporate a great deal of moisture. The use of fragmented fibres greatly increases the evaporation surface. With fresh air streaming through, significant amounts of moisture are forced away through the dynamic of the body‘s heat.
