These sheets appear to be an excellent percale sheet, which is what I was looking for. They are a medium weight and provide that cool, crisp sensation everyone wants with percale. There was a slight sheen when I opened the package but this disappeared after the first washing. They do wrinkle but that is the nature of percale and I just don't care. They makes a nice rustling sound which reminds me of nice hotels I've stayed in the past. The color is true to the photo.My only complaint is the elastic on the fitted sheet. While it does go all the way around, a must in my opinion, it is cheap and thin and, I suspect, will not last very long. For $100, I expect better than this. Hopefully I am wrong and I will get years out of these sheets. I will not order a second set until I see how long these last.UPDATE! - My original concern regarding the elastic was unfounded. These sheets have been washed weekly and used daily, and the elastic is as strong as the day I received them. Will be purchasing a second set!
