Percale Duvet Cover

Our percale collection is made with 100% long staple cotton fibers. The percale weave creates an airy and breathable fabric perfect for hot sleepers and a cool, crisp feel that gets softer with each wash.

Technically speaking, thread count refers to the number of threads per one square inch of your sheets. When we started designing our bed sheets, we realized that while we're taught to look at thread count, we weren't really sure why. Through research, it became clear that higher thread count doesn't always mean higher quality or softness. In fact, more threads can actually make sheets heavier and less breathable.

All of our bed sheet sets are machine washable. We recommend washing your bed sheets in cold water on a gentle cycle. Tumble dry low and remove from the dryer as soon as possible to keep them from wrinkling. Warm iron as needed. To keep your bed sheets looking good as new, use a non-chlorine, oxygen bleach with each wash and wash them every one to two weeks.
