Textile configured to promote cooling

Abstract

Aspects herein are directed to textile that includes a first layer formed from a first plurality of yarns or fibers. The first layer includes a first set of apertures, each aperture having a first opening size. The textile further includes a second layer formed from a second plurality of yarns or fibers. The second layer includes a second set of apertures. Each aperture in the second set of apertures is axially aligned with a corresponding aperture in the first set of apertures. Each aperture in the second set of apertures has a second opening size that is smaller than the first opening size of apertures in the first set of apertures. The first layer is relatively more hydrophilic than the second layer.
