This Sheet Set is made from 100% cotton for a breathable and relaxed comfort. Jersey Sheets are knit - not woven - so they are naturally stretchy, wrinkle resistant, and breathable. Jersey cotton sheets have become quite popular because they feel like you're sleeping in your favourite comfortable t-shirt. Because of their warmth and huggable feel, they can make a great choice for the colder nights. You can then decide to pay for the postage or cancel the order.
