An apparel item configured to reduce the perception of cling is provided herein. The apparel item comprises a first set of outwardly-projecting nodes on a first portion of the apparel item, a second set of outwardly-projecting nodes on a second portion of the apparel item, and a third set of inwardly-projecting nodes on a third portion of the apparel item, where the third set of nodes is positioned between the first set of nodes and the second set of nodes. The first and second sets of outwardly-projecting nodes comprise apertures that provide a communication passage from an outer surface of the apparel item to an inner surface of the apparel item. Besides reducing the surface area of the apparel item that comes into contact with a wearer's skin surface, the nodes also facilitate cooling the wearer and speed up drying times of the apparel item when being worn.
