Breathable in an optimal way

The compact, pore-free Sympatex membrane works unlike other membrane technologies on the basis of a physicochemical principle.

The hydrophilic component of the membrane absorbs body moisture and transfers it to the outside through evaporation. In this way the vapor molecules are transported to the outside along the hydrophilic molecular chains.

The molecular structure (hydrophilic components) of the Sympatex membrane swells due to humidity and therefore offers space for the transport of water vapor and for rapid evaporation.

This effect increases with the difference between temperature and humidity. A partial pressure difference, generated by different temperatures and humidity of the air inside and outside, constitutes the physical driving force that carries the water vapor through the membrane.

Environmental characteristics

Eco-friendly PES material, easy return in the recycling process together with textiles / PES.
0.14 T CO2 emissions for each linear km; with Sympatex: full C02 compensation since 2017
Water consumption 1.6 m / cubic per linear km
Heat recovery, products / combustion gases similar to those of wood

Dynamic climate regulation

The more intense the body sweating, the greater the amount of moisture that the membrane is able to transport to the outside.
The effectiveness of "Smart Dynamic Membrane Technology" therefore increases dynamically and in relation to needs. As a unit of measurement for transpiration activity, the Ret value is used, among others.
It designates the resistance that a material opposes to the passage of water vapor. A Ret index of less than 6 indicates excellent breathability. The Sympatex membrane reaches peaks with values ​​of 0.5
