Exclusive to Coyuchi, our crinkled percale is perfectly broken in right out of the box and just right for every season. To create our softest, most relaxed percale yet, we took pure organic cotton and applied proprietary spinning and weaving to create a washed fabric with a lightly crinkled effect all over. The result is what may be our favorite sheeting yet: Breathable, comfortable, beautifully rumpled sheets that wash and wear well over time.

Love this!. It feels like percale should; soft and crisp. It is just the right weight, not too heavy or too light. The only thing that is odd is that there are ties at the bottom to secure the duvet and not the top which seams it should be the other way around. It's fine because I wasn't expecting ties anyway. I would order again.. Lynn. Palm Springs, CA. Sun Jul 23 2023
