Abstract: An apparel garment that includes individual fibers exhibit proper moisture wicking properties and that have been infused or coated (or both) with far infrared materials is provided. The combination of suitable fibers and far infrared materials imparts a unique effect to the apparel garment wherein the far infrared materials will physiologically and therapeutically impact the user's circulatory system to dilate surface capillaries, break down water clusters, and allow for toxin removal at the apparel/skin interface. Coupled with the overall moisture wicking capability, surprisingly the inventive garment actually provides a cooling effect during an exercise event in a warm temperature environment and a warming effect during an exercise event in a cold temperature environment. The utilization of such a garment to impart such an exercise-activated cooling or warming effects, and thus the ability to allow the user greater comfort during any type of workout, is also encompassed within this invention.
