X-bionic Energy Accumulator 4.0 Shirt Black

The body produces varying amounts of heat in different regions of the body. Those coming from the chest and back are particularly high due to the need to protect organs interni.il the 3D system Bionic Sphere® with Thermo Syphon Technology® leaves a thin film of moisture on the skin without the body Sense a wet sensation.
The Sweat Traps Technology® then transports excess sweat and evaporates it, thus it deforms through thermal dynamics. The remainder constitutes only a thin, comfortable, thin and refreshing layer of moisture.
Of course in the absence of sweat there is no cooling.
With freezing temperature the entire channel system acts as an insulator during recovery rest phases. This avoids the risk of excess cooling during the activities.
