This allows it to do two important things at once: retain your body heat more effectively and help wick away moisture from perspiration. This means you'll experience dryness, comfort, breathability, and less dampness than with regular underwear. Because good thermal underwear moves flexibly with you, your freedom of movement is also maintained. This makes it ideal for everyday wear, sports activities, and long hours outdoors in cold weather.

You may also see terms such as thermal clothing, thermal underwear, and base layer. These terms are often used interchangeably for functional underwear that helps retain heat and wick away moisture.
