Percale sheets (pronounced “per-kail”) are made with cotton. These have a plain weave — one yarn over, one yarn under — that creates a matte, crisp finish. These sheets get softer with each wash and are best for hot sleepers and warm weather. They aren’t wrinkle-resistant, so it’s best to remove them from the dryer immediately following the end of the cycle. 

 To sum up, the weight of a duvet insert plays an important role in determining its comfort and adaptability to different climates and personal preferences.  Whether you choose an ultralight, midweight, or heavy-duty duvet insert, understanding the features of each type will help you make an informed decision and ensure a good night's sleep.
