Just like with most things, though, not all cotton plants are created equal. Egyptian cotton that grows along the Nile River produces the highest quality textiles because of its extra-long staples. 

Your t-shirts are made out of it, cotton candy is named after it, and it’s the most common material used to make bed sheets. It’s breathable, forgiving when removing stains (adios blood stains), and stays cool. Cotton sheets also soften up with time and washes while maintaining their durability.
