1. A multifunctional material system, comprising:
a variable-permeability layer applied to a substrate; and
a desiccant layer applied to a surface of the variable-permeability layer that is opposite to another surface of the variable-permeability layer adjacent the substrate;
wherein the system moves water from the variable-permeability layer to the desiccant layer when relative humidity is greater adjacent the variable-permeability layer than the desiccant layer, and when the relative humidity is greater adjacent the desiccant layer than the variable-permeability layer, water is absorbed by the desiccant layer to inhibit water from reaching the variable-permeability layer, and
wherein the variable-permeability layer and the desiccant layer are separate and distinct from each other.
