Received the Purity Home 144TC Percale Organic Cotton Pillowcases, KPC, White.  They feel crisp, cool and soft on my king size pillows.  The cases fit them well.  I like that they are high moisture wicking and durable for all season use.  I also like that they are made from organic cotton with open weave construction to allow air flow and there are no harmful substances used while manufacturing.  Slept on them last night and they were very comfortable.  I like that these are made using sustainable manufacturing and responsible farming.  I can see me using these for a number of years and checking into buying more of them.  The only drawback I had with these is that they came out wrinkled from the dryer but smoothed out when you put them on the king size pillow.
