Abstract
A splash resistant multi-layered structure is provided. The structure includes a specific arrangement of layers of material and a plurality of three-dimensional spacers that helps prevent penetration through the structure by a fluid that contacts an outer surface of the structure due to a state of forced separation that exists between two adjacent layers of the structure due to the presence of the plurality of three-dimensional spacers positioned between the layers. The plurality of three-dimensional spacers can be positioned on one of the adjacent layers of the structure such that a distance at least as large as the maximum height of the plurality of three-dimensional spacers separates the two layers from each other and can be present on a layer of material in a continuous or discontinuous pattern or can be present on a layer of material in a random fashion. The presence of the three-dimensional spacers can reduce the basis weight or eliminate one or more layers of the structure, which, in turn, can reduce thermal resistance, lower the pressure drop across the layers of the structure, and reduce the overall weight of the structure to enhance breathability and comfort.
