Better Hair: Made of 100% polyester. It is ideal for those with curly hair. Better Sleep: The silk-like fabric on this pillowcase set provides long-lasting durability against wear and tear. An envelope closure design ensures the pillow insert stays in place without sliding.
I like these pillowcases, hair is a lot less messy, they are a bit cooler, but I live in the north of Scotland os no high temps like London. Would definitely buy more.
