Cotton is one of the most comfortable natural fibers to wear against your skin. You can choose from 2 different weights of 100% cotton thermal underwear. We carry it in an expedition weight for those extremely cold days. We also carry 100% cotton long johns in a regular heavy weight for mild cold to very cold temperatures. 100% cotton is recommended for use wherever there is fire danger as it will not melt into your skin like synthetic fibers will. These thermals are great for air force pilots and other armed forces use.
