Super pure wool from sheep raised organically without antibiotics, hormones or other chemical treatments and tested free of chemicals. Super processed organically (Certified by Oregon Tilth) to remove vegetation, dust, and excess oils. The result is a lofty, clean wool that does not have the pungent odor of many natural wools. They are then covered with silky soft organic cotton sateen. They are hand-tufted and a bit more lofty, fluffy than quilted wool comforters. The comforters are warrantied for 1 year against manufacturer defects. Comforters arrive completely protected and sealed in food grade polyethylene to retain purity. Spot clean.
