I wore these over tights during the winter to protect against the cold. I've worn them about 5 times. They have been washed. Made of 100% cotton, they are gentle on the skin, and the washing instructions are printed on the inside. The absence of seams at the hem and sides reduces itchiness, and the lines of underwear are less likely to show through. There is some overall pilling.
