The material is closely knitted and tightly woven so that the base layer retains the warmth produced by the body. The extra layer allows better moisture retention, and helps to keep the skin dry.

In addition to holding a good amount of heat, it also works to keep sweat away from the skin. This type of thermal underwear "breathes," It keeps the wearer dry and warm by wicking moisture away from the skin.

The fibers in the fabric absorb the moisture on the skin and pull it away from the body. This prevents the wearer from becoming cold, soggy, and frozen.
