I received the sleep zone satin pillowcases recently and absolutely love the benefits of thse pillowcases - they help with hair breakage and things like your skin. I love they stay cool in the summer and help with temperature control.The grey match my bedding and they couldn't be a better fit with our bedroom decor. I couldn't ask for better pillowcases to use, I've been using them a few weeksn and they really help with hair breakage. I love these pillowcases.
