I’ve tried several “silk” or satin-ish pillow cases and I’ve ended up sweating to death and feeling stuck to them. The material always felt too thick and really cheap, and would tear up or have rips after the first wash. This one is nothing like those! It washed up perfectly [delicate cycle and med dry] and it’s by far the softest one I’ve ever felt. I didn’t get hot at all, it stayed completely cool and did not wrinkle while I slept or stick to my face, and I wear serums and moisturizers to bed. My hair didn’t frizz and my skin wasn’t dried out when I woke up. I love this one and plan to get another. I ordered a king and it was perfect for my king sized pillow. Great buy 👌🏽
