Like Pima cotton, Egyptian is extra-long-staple cotton, making it equally exceptional in softness, vibrancy, and performance. They even share a scientific name! The only difference between the two? Egyptian cotton is grown in the hot, dry climate of the Nile River Valley in Egypt. It is the cotton of exceptional quality — that is, if it can be verified with true Egyptian origins. Sadly, many of the kinds of cotton sold as "Egyptian" aren't Egyptian at all.
