C-CHANGE

Functions:

Open in response to heat or increased activity:
At high temperatures, the structure of the c_change™ membrane opens as the moisture levels rise. Excess heat can escape to the outside air.

Closed in response to cold or reduced activity:
Due to the lower level of moisture development in cold weather, the structure of the membrane closes, retaining the heat.

COLD / LOW MOISTURE
In Nature:
1 Fir cone is closed
In the Membrane:
2 Polymer structure condenses, thus providing better insulation.
3 High level of heat retention and moisture vapor permeability combine to create a pleasant climate.
4 Durable wind and water proof.

WARM / HIGH MOISTURE
In Nature:
1 Fir cone opens up
In the Membrane:
2 Polymer structure opens up and becomes extremely moisture vapor permeable.
3 Excess heat and moisture can escape to the outside air.
4 Durable wind and water proof.

c-change results:

• c_change™membrane, in contrast to a hydrophobic membrane system, allows 25% more moisture to escape from the inside to the outside within the same period.
  
• Alteration of the breathability at different temperatures and in different moisture situations
  
• Moisture management – quantity in relation to time
