This superior 40/1 forty singles long staple organic cotton is ring spun, napped, and brushed to achieve the softest and most touchable medium weight interlock manufactured in the USA. Our low carbon and pesticide free tumble dried organic cotton medium weight fleece is dyed with fiber reactive dyes in a closed loop system where the water is perpetually recycled. From the yarn to the finished fabric, the entirety of the manufacturing process occurs within 150 mile radius of the Spiritex Asheville, NC headquarters.
