Review title is Cute, but hard, and very uncomfortable to sleep in [SEP] The product design itself is great. However, it's so stiff, it moves off your head. I do like the concept tho, as normally I just use a robe tie, which I can sleep in. My hair is very long, and I am able to wrap this around ALL of my hair with no problem; but you can't sleep in it. It is very stiff and painful to sleep in. I couldn't even lay any way without it pushing forward and the hair popping out of it. Great concept tho, but I would use a robe tie vs this, or just wear this around the house, and not to try and sleep in it.
