GOTS Organic cotton is grown from non-GMO seeds and prohibits the use of the kinds of chemicals commonly used in textile processing that can be harmful, helping to protect the environment, farmers, factory workers, and end consumers. It also conserves natural resources. GOTS certified: GOTS is recognized as the world’s leading textile processing standard for textiles made from organic fibers. With a percale weave, the threads go over and under in two perpendicular directions, creating a tighter weave that offers exceptional strength and long-lasting good looks. The lightweight sheet wicks away moisture, making it extremely breathable. Even more, this percale has been brushed to a peach-like finish for a notably softer hand feel. Thread count refers to the number of threads that make up one square inch of fabric. Typically, the finer the threads that can be woven together, the softer the fabric. Thread counts can range from 150 to 1,000. This lower-range thread count is appreciated for its breathability and durability. Thanks to its Technofit technology, the set’s fitted sheet stays more securely in place on the mattress. An extra-thick elastic band around the perimeter of the fitted sheet minimizes any shifting, making it a great alternative to other sheets that can annoyingly and repeatedly slip out of place.
