The material is really nice, super comfortable, the best things you can expect from a underwear. For those like me that like to check the fabric composition, this models are 88% polyester and 22% spandex. They are not that silky feel of a underwear made of 87% nylon and 12% spandex that is soooo good on the skin, but is similar to it, not as breathable as that other kind, but more sturdy/resistant.
