Fabrics and garments may include “dimensionalized” structures. The fabric may be “dimensionalized” by integrally forming a plurality of self-standing fabric surface modifying elements in the fabric material to thereby provide a fabric contact level different from (and/or reduced in surface area as compared to) the fabric base level. Garments may include this “dimensionalized” material, e.g., positioned at various locations to promote better evaporative cooling of the body or heat retention, such as along the wearer's spine, sides, and/or other locations that release substantial heat. The “dimensionalizing” structure may be formed in the material, for example, by molding, rolling, embossing, calendering, stretching, crimping, pressing, heating, and/or the like.
