Calvin Klein men's briefs Calvin Klein men's briefs will delight all men. The cotton material with soft hems fits perfectly on the body. The briefs fit well and you don't have to worry about you being cut somewhere. The woven rubber is pleasant, does not strangle or bite anywhere. The important information is that they are about a third the size of other brands. Please check the selected size with the size chart (if you have not already tested Calvin Klein underwear and you know your size). They are packed in an original plastic box.
