These is a very comfortable sheet set especially in hot weather. It whisks the sweat and warmth from you. So much more comfortable than cotton. Washes very well and retains that comfortable feeling. 
Am using it for a roll away bed that I have for guests. Also fits true on a regular twin bed. Color stays fast.
Will want to order more like this for our rooms. Its that refreshing in hot and sometimes very humid weather.
Prior to this was always a 100 cotton person. With this sheet I have learned that cotton really retains your body heat. You sweat more and it feels uncomfortable. This sheet set doesnt have that which I have learned.
Many locations are getting scorching weather. And its harder to sleep with that kind of weather, especially with heat retention of the air and your body heat.
Consider reconsidering cotton and use a set like this!
Highly recommend!
