Panties that are 90% or more cotton have some distinct advantages over synthetics, in that they're soft, breathable and absorbent. Many doctors will advise women to only wear cotton if they have frequent infections caused by the build-up of moisture, which encourages the growth of various microbial organisms. Organic cotton is even more amenable to comfort and feminine hygiene, since it is free of irritating pesticides and other chemicals. Panties that have 10% or less spandex add a bit of stretch. Among the makers that offer these fine quality cotton-blend or 100% cotton panties: Calida, Elita, Hanro, fine lines, Knock out!, Cottonique and others.
