These sheets are absolutely smooth, 100 % cotton, cool and breathable. With hot and humid summers these sheets made a difference with 400 tc percale. I love the cool, crisp feel. Just knowing the fact that these sheets are sustainable-earth friendly are a definite buying factor for future purchases. They are a bit wrinkly after washing but then again I dried them with low heat. But who cares, anyway the smoothness and feel of these sheets totally sold me. By the the top/bottom are tagged.
