I really like crisp sheets,but they also have to be soft and smooth. That's exactly what you get with the Percale Organic Cotton pillowcase. These pillowcases are comfy and they stay cool all night, which is a big plus for me personally. I can't stand to have restless nights from being awaken because of getting hot. The percale keeps your head cool throughout the night. Now anytime I go to buy new bedding sheet sets I always look for percale. They keep getting softer with every wash and still keep their cooling effect. If you are a hot sleeper or wake up from getting hot, you should try the percale organic cotton sets, you will be amazed at how soft and cool they feel.
