The Standard Comforter is filled with wool from organically raised sheep with certified organically processing by Oregon Tilth. The outer fabric is organic cotton damask. These wool comforters are hand-tufted for a soft, fluffy feel. The air trapped between the fibers responds to your body temperature, while perspiration is absorbed and released slowly through evaporation so you never wake up overheated or chilled from night sweats. Pure Rest's Eco Wool is so much purer and cleaner than virgin wool. Taken from organically raised sheep in the hills of Oregon and processed at a facility that only produces natural wools according to organic standards.
