How does Dermizax™ work?
The ultrathin Dermizax™ membrane exploits the movable polymer molecules in order to absorb perspiration efficiently in the form of moisture on the inside of the laminate. The moisture is then quickly forced through the laminate so it can evaporate on the outside. The molecules also have the ability to move faster at high temperatures or high levels of activity. This means that breathability improves when you get hot and sweaty. The Dermizax membrane does not have micropores that can be obstructed by dirt, which is why the membrane maintains its unique function even after years of rough use.
