Outlast® Temperature Regulation stores and releases body heat.
It works to keep the wearer’s temperature not too hot... not too cold... but just right, over a broad range of environments and activity levels.
When your activity level or the outside temperature increase, the Outlast® thermocules that contain the phase change paraffin begin to change from a solid to a liquid which provides you with a comfortable sensation of thermal equilibrium. The energy required to activate this process comes from your warm body or the rising ambient temperature.
When you begin to cool down, Outlast® thermocules begin to change back from a liquid to solid. In this phase change, the energy that was absorbed by the thermocules while you were active is returned to you.
With the new moisturetransfering material Outlast® functions in active use too.
