Cotton is generally recommended by experts as the healthiest and most comfortable fabric for underwear. Not only is it soft, but it is also breathable, so you are less likely to overheat and feel uncomfortable in a great pair of cotton undies. It can be a challenge to find fully 100% cotton styles since many cotton options are a little over 90% cotton with the rest of the fabric blend being spandex or elastane to help stop the fabric from stretching out.
