PATENT PENDING, Drawstring adjustable satin lined hat! The band has a drawstring so you can adjust to fit your comfort level. Hats are made with a lightweight polyester satin lining. The satin provides protection from the harsh fibers of your pillowcase, the friction that causes tangles while you are sleeping and the outside elements that damage hair on a daily basis. It is great for all types of hair, especially natural hair & naturally curly hair. It can also extend the life of your hair-do because it protects your hair while you sleep, so your hair will look just as good when you get up, with only a touch up required. Why buy from us? Our company is focused on producing high-quality products that are also stylish and fun and will make a difference in your daily life. We also have a social mission of working with a manufacturer who employs those most marginalized by society.
